ParkerVision filed its first patent for its RF technology, called D2D, in 1996 and has, over the years, aggressively touted its technical advantages as “revolutionary”.  Ten years later, however, the net result from D2D technology is no revenue, no customers, no partnerships, and no licensing agreements.  The company’s efforts in consumer wireless products were shut down in the summer of 2005 after many “discussions” with customers.

In January, 2005, ParkerVision announced an extension of D2D technology to power amplifiers, called D2P.  They announced that prototypes would be sampled to customer and a design win would be achieved by the end of the year.  To date, there is no news on any progress with D2P technology.  Like its D2D counterpart, D2P technology is late to market, has no datasheets available to prove its “superior” performance, and customer “dialogues” are not yielding meaningful design wins. 

The following section summarizes ParkerVision’s press releases related to D2D and D2P
ParkerVision D2D Press Releases in the 1990’s
In late 1997, ParkerVision announced the invention of a universal direct conversion receiver chip that it believes “represents a major breakthrough in wireless RF receiver technology.” In July 1998, ParkerVision announced that its wireless technology has the capability to become the new standard for RF receiver technology. In October 1999, ParkerVision announced a licensing agreement with Symbol Technologies where ParkerVision's D2D technology would be incorporated into the majority of Symbol Technologies' future WLAN products.  Nothing came of that agreement.

ParkerVision D2D Press Releases in 2000
In January 2000, ParkerVision announced the completion of a RF transmitter demonstration platform that confirms its D2D technology exceeds requirements of GSM cellular telephone transmitter specifications. In February 2000, ParkerVision, announced it would offer an integrated RF front-end integrated circuit (IC) for Wireless LAN products that would lower cost, size, and power consumption while maintaining performance.  No datasheet was ever made public about the actual performance of these chips.

In May 2000, ParkerVision reported the results of its latest downconverter demonstration platform to verify that the D2D technology provides the necessary performance to support standards-compliant radio transceivers. ParkerVision also announced in May 2000 that it received its third D2D technology patent from the United States Patent & Trademark Office, where U.S. Patent 6,061,555 covers an application of the its D2D direct conversion receiver and transmitter technology using its system architecture to enable robust signal reception in environments that contain jamming signals.

ParkerVision D2D Press Releases in 2001
In May 2001, ParkerVision announced that it unveiled its D2D 802.11b Wireless LAN direct conversion transceiver chip in demonstrations at the Networld+Interop networking trade show in Las Vegas and also announced that it has organized its entire wireless activities under a newly created division doing business as Direct2Data Technologies. Again, no datasheet has ever been published on these chips.

In July 2001, ParkerVision announced it received its fifth U.S. patent for its D2D wireless semiconductor technology, which is in the process of being commercialized for the wireless LAN and cellular markets, where U.S. Patent 6,266,518 was issued to ParkerVision by the United States Patent & Trademark Office.

ParkerVision D2D Press Releases in 2002
In March 2002, ParkerVision announced that it received its sixth U.S. patent for its D2D wireless technology, where the patent covers some of the fundamentals of the D2D transmitter technology such that a single unified operation an on-channel RF carrier is achieved in a direct up-conversion from a baseband information signal. In April 2002,
ParkerVision announced that it received its seventh U.S. patent for its D2D wireless technology covering fundamentals of the D2D receiver, transmitter, and radio frequency filtering technologies and encompassing a wide spectrum of consumer products that can benefit from use of ParkerVision's D2D technology, such as wireless LANs and cellular telephones.

In July 2002, ParkerVision announced that it completed the development and successful testing of wireless LAN radio transceiver chips based on its D2D technology.  No datasheet was ever published for these transceiver chips.

ParkerVision D2D Press Releases in 2003
In September 2003, ParkerVision announced it has launched for immediate availability a wireless LAN card marketed under the brand name Horizons Wireless which greatly improves the distance and data rate performance of any existing 802.11b or "g" compliant network and works with all existing access points. In November 2003, ParkerVision's Direct2Data Technologies Division signed its first retail distribution contract with TigerDirect, Inc.

When this card was evaluated, it was discovered that the majority of the gain in distance and data range were not the result of the D2D chip, but rather use of a high gain antenna from Skycross (www.skycross.com ) and external low-noise pre-amplifier, more raw power in the transmitter, and redundancy in both antennas and receivers! 

ParkerVision D2D Press Releases in 2004
In July 2004, ParkerVision announced it acquired the Aero 2000 cordless phone from Consumerware for about $1 million, which would allow ParkerVision to package its wireless technology in a ready-to-use phone.   ParkerVision never commercialized the cordless phone and was unable to find an OEM customer for it.

ParkerVision extended its marketing campaign of its SignalMax wireless products in 2004.  However, the more complex architecture made the cards too expensive to compete with LinkSys, D-Link, and Netgear products having comparable performance, so that the SignalMax product line resulted in less than $1M in revenue, and most of the inventory was written down.

ParkerVision D2D Press Releases in 2005
In January 2005, ParkerVision completed its testing of a family of new D2P RF power amplifiers that promise to reduce transmitter power consumption by 50 to 80 percent, stating it would target its new chips to “anybody building a wireless RF product that's portable.”
In July 2005, ParkerVision stopped making wireless communication products, less than two years after introducing a line of wireless home networking equipment and hiring people specifically to help them become a consumer products seller.  No other press releases regarding D2D or D2P products or market penetration have been made to date.

ParkerVision Confirms D2D Technology Supports the World's Most Popular Digital Cellular Communications Standard (January 31, 2000)
GSM Transmitter Demonstration Platform Uses Standard CMOS Semiconductor Implementation and Zero IF Architecture
ParkerVision, Inc. (NASDAQ:PRKR), announced today the completion of a RF transmitter demonstration platform that confirms the Company's Direct2Data(TM)" (D2D) technology exceeds the requirements of the GSM cellular telephone transmitter specifications by significant margins. GSM compliant performance was achieved using the identical D2D-based transmitter hardware that verified D2D IS-95 CDMA transmitter compliance. The D2D demonstration hardware is implemented in standard bulk CMOS and using a true Zero intermediate frequency (IF) architecture, eliminating the need for all IF amplifiers, filters and other supporting IF components. The Company believes this achievement represents another significant step towards the commercialization of its unique wireless technology as well as a significant opportunity to reduce cost, size, and power consumption in CDMA and GSM RF transmitter applications.

Jim Baker, Vice President of Business Development, stated: "This is another significant achievement in our progress towards confirming the benefits of the D2D technology in a variety of important wireless applications. Since we have now verified that the same D2D transmitter meets the requirements of both CDMA and GSM applications, the development of multimode wireless telephones incorporating CDMA and GSM capabilities can be greatly simplified. Dual mode CDMA and GSM transmitters based on D2D technology can now be realized in standard CMOS while reducing power consumption, parts count, size, and cost compared with today's traditional hardware approaches. This provides for the opportunity to create very cost-effective stand-alone chips. Alternatively, the entire RF to baseband function can be easily integrated within the cell phone's CMOS baseband processor IC, eliminating a separate RF conversion chip altogether."

Baker continued, "We are very excited about this result and are confident that the D2D technology would deliver similar successes in CDMA and GSM receiver applications. This moves us one more step towards our goals of wireless products which incorporate important multiple communications standards in a cost-effective yet high performance manner."

GSM is currently the world's most popular digital cellular standard. The Company believes it is a significant accomplishment to address this specification using standard CMOS semiconductors and a true Zero IF architecture. The current D2D GSM transmitter demonstrator exceeds key performance requirements of the GSM standard by significant margins.

For example: The output power level of the D2D GSM transmitter was measured at 30 dBm and the spectral mask requirements were achieved with significant margins. -- Adjacent channel interference rejection specifications are met with at least a 3.8 dB margin across the deviation band specified in the ETSI GSM specification. The GSM specifications allow no more than 5 degrees RMS and 20 degrees peak deviation from the ideal phase trajectory. The D2D GSM transmitter achieves a phase deviation of better than 2.5 degrees RMS and less than 6 degrees peak.

No additional baseband processing or DAC speed/resolution is required to meet these specifications. D2D achieves very high linearity radio performance per milliwatt and excellent preservation of the information content of the signal.

ParkerVision Will Offer an Integrated RF Front-end Integrated Circuit for Wireless LAN Products (February 25, 2000)
ParkerVision, Inc. (Nasdaq: PRKR) would offer a highly integrated RF front-end integrated circuit (IC) for Wireless LAN products that would significantly lower cost, size, and power consumption while maintaining excellent performance, the Company announced today at the Wireless Symposium/Portable by Design Conference in San Jose, Calif.
Jim Baker, Vice President and General Manager for ParkerVision's wireless business, stated, “The market for Wireless LAN (WLAN) products is growing at a substantial rate. ParkerVision intends to capitalize on this market growth with a commercial product line incorporating the company's revolutionary D2D radio technology. The D2D technology enables the implementation of a RF direct conversion transceiver for challenging radio applications in standard CMOS, providing unprecedented integration possibilities.”

According to a study by Cahners In-Stat Group, the enterprise WLAN market would expand at a 25% compound annual growth rate from 2000 to 2004, reaching $2.2 billion in worldwide sales. Many major networking and communications vendors including 3Com, Cisco, Nortel Networks, Lucent, Nokia, and Ericsson now offer Wireless LAN products. Recently, mainstream PC OEMs such as Dell, Compaq, and Apple have also begun offering WLAN products.

Mr. Baker said, “As WLAN products become increasingly popular and the market for them more competitive, vendors are under pressure to simultaneously reduce cost and size, increase performance, and add functionality. As the cost of WLAN products decline and data rates increase, they become attractive alternatives to traditional wired networks, thereby accelerating volume. The D2D architecture would allow manufacturers to not only reduce components cost and power consumption but also simplify the design and manufacture of these products.

“ParkerVision's proprietary D2D technology's performance characteristics enable a roadmap to higher data rates. The initial ParkerVision wireless product would be based on the IEEE 802.11-b 11 Mb/s standard in the 2.4 GHz band. Our product line would extend to encompass the IEEE 802.11-a higher rate products in the 5 GHz band as well as other higher rate standards. D2D also enables the practical development of combination devices, enabling vendors to incorporate multiple wireless communications standards in a single device, for example, IEEE 802.11 and Bluetooth,” he noted.

New Patent for ParkerVision (May 09, 2000)
ParkerVision, Inc. (NASDAQ NMS:PRKR) received U.S. Patent 6,061,551 covering the fundamentals of its Direct2DataTM (D2DTM) direct conversion radio receiver technology. .,. ParkerVision is in the process of commercializing the technology, which the company believes marks an innovative breakthrough in cost-effective high quality radios for wireless communications.

The 551 patent issued by the United States Patent & Trademark Office contains 204 claims and cites over 600 references. It is part of ParkerVision’s overall intellectual property strategy, which includes more than 50 other patents pending. The company continues to pursue the filing and protection of its patents in the United States and abroad.

The patent covers a unique radio frequency (RF) receiver architecture embodying two novel concepts – energy sampling and matched filter theory applied to the RF carrier to extract the data from the carrier. These elements of the architecture contravene traditional RF engineering teachings, but it is this non-traditional architecture which the Company believes enables it to design radio circuitry which allows for wireless devices that are smaller, more reliable, and use less power than those built using traditional heterodyne RF components.

"We believe D2D has the potential to dramatically impact the entire wireless industry in terms of product enhancement and cost and power savings," said Jeffrey Parker, Chairman and Chief Executive Officer. "Therefore, we are putting in place the appropriate intellectual property protection as we continue to commercialize the technology. Securing patent protection helps us pursue maximum potential for D2D in both chip sales and licensing opportunities, and in the process continue to build shareholder value."

"The 551 patent represents an important milestone for the company," commented ParkerVision’s Chief Technical Officer and lead inventor of the technology, David F. Sorrells. "The technology embodies several counterintuitive concepts, including some which are actually taught against in the relevant literature. The combination of energy sampling and matched filter theory applied to an RF carrier creates the foundation for the implementation of our direct conversion technology. We believe D2D resolves in practical implementations the multitude of performance shortcomings that have kept direct conversion radios from being used in many wireless applications."

ParkerVision’s Chief Staff Scientist, Gregory S. Rawlins, commented, "Before selling our company to ParkerVision, we extensively evaluated the D2D technology and the fundamentally new theories embodied in the invention. D2D technology enables very practical high performance direct conversion radios which can be easily implemented in any semiconductor process including standard CMOS, occupying a small footprint, and delivering excellent performance with low power consumption. This makes possible much higher levels of radio integration on chip."

ParkerVision Reports Results of its Downconverter Platform (May 11, 2000)
ParkerVision, Inc. (NASDAQ: NMS: PRKR) reported today that the results of its latest downconverter demonstration platform, incorporating an enhanced version of its D2Dtm direct conversion RF technology in low-cost 0.35-micron standard CMOS integrated circuits, verify that the D2D technology provides the necessary performance to support standards-compliant radio transceivers for IS-95 CDMA, GSM, IEEE 802.11 Wireless LANs, Bluetooth and other important wireless applications.  Accordingly, ParkerVision believes this implementation of D2D provides the most compelling combination of performance attributes of any direct conversion technology available for use in mobile wireless applications.

Jim Baker, Vice President and General Manager stated, “The success of our downconverter demonstration platform marks important progress toward ParkerVision’s realization of practical hardware based upon its D2D technology for key wireless communications markets.  The performance measured from our latest implementation enables us to formalize our development efforts for a low-cost, highly-integrated IS-95 CDMA IC product line.  The significance of the D2D technology is that it has demonstrated excellent conversion performance while enabling cost-effective true Zero IF radio architecture, eliminating the need for the intermediate frequency amplifiers and filters currently required.  D2D-based radios implemented in standard CMOS occupy very little IC die area and are able to process complex wireless communication modulation methods for frequency bands exceeding 4 GHz using 0.35-micron technology and over 6 GHz using smaller geometry processes.  We believe that D2D technology has the potential for tremendous commercial appeal because it simultaneously achieves the goals of small size, low power, low costs, and high-performance.”

Compliance with key IS-95 CDMA RF specifications was shown using the new 0.35-micron CMOS implementation.  The new downconverter platform was connected to the previously announced D2D-based CDMA transmitter platform.  This configuration was tested in a mobile-to-mobile mode, a severe test scenario.   In this configuration a back-to-back system RHO of 0.971 was achieved.

Mr. Baker pointed out, “These results comfortably exceed the IS-95 CDMA specifications for Rho of 0.912 minimum for a single transmit or receive path.  In the past, unsuccessful attempts have been made to apply direct conversion radios to challenging applications.  The latest platform clearly demonstrated that the D2D technology does not suffer from the known shortcomings of other direct conversion approaches based on traditional RF techniques.  Our D2D technology had made the direct conversion architecture issues of LO re-radiation and DC offset manageable in a straightforward manner.”

The performance of the D2D technology implemented in 0.35-micron CMOS offers improved linearity, DC Offset and LO re-radiation performance over the previous 0.5-micron CMOS implementation.  The demonstration platform operates using a sub-harmonic LO that is 1/3 of the RF frequency.  This sub-harmonic operation provides significant value when compared to traditional heterodyne solutions through the simplification of the frequency plan, the minimization of self interference, the reduction of power consumption and the ability to process high operating RF frequencies using low-cost, standard CMOS.

ParkerVision Announces RF Power Amplifiers that Reduce Transmitter Power Consumption by 50% to 80% (January 20, 2005)
ParkerVision, Inc. today announced that it is introducing a new product line of ultra-efficient, low-cost RF power amplifiers targeted to companies that design and manufacture wireless RF products. The initial product line is designed for use in cell phones, cordless phones and for Wi-Fi, Bluetooth and VoIP products and applications. This breakthrough in cost, size, and performance is made possible by the company's expertise in converting traditional analog designs into advanced digital architectures. ParkerVision's power amplifiers incorporate a proprietary all digital circuit architecture that replaces traditional analog circuitry.

ParkerVision's power amplifiers would significantly extend battery life in mobile wireless RF products and help designers improve cost and size by reducing the size of the battery. In certain applications, such as Wi-Fi, ParkerVision's power amplifiers would enable manufacturers to provide networking gear that delivers higher data rates at greater distances, with significantly increased coverage and reliability, by providing greater RF transmitted power than is currently available in the market today.

The level of power efficiency achieved by ParkerVision's proprietary digital power amplifiers replaces the commonly used analog RF power amplifiers used today and far surpasses the efficiency of such offerings. Alan Varghese, Principal Analyst with ABI Research, states "today's wireless users demand higher performance devices which place increasing demands on battery life. The cost-saving desire for smaller batteries and the demand for increased range would be important factors in manufacturers' design decisions moving forward."

"Our products would empower manufacturers with a new solution to create unparalleled choices in efficiency, cost, size, and performance for their wireless products," commented Jeffrey Parker, ParkerVision CEO. "We would immediately begin working with manufacturers to configure the offering to their needs and provide samples mid-year, with volumes available later in the year. We are targeting high volume as well as fast growth applications. Our product line, built from common low cost silicon semiconductors, would incorporate into single chips the same ease of design that manufacturers have come to rely upon from multi-component modules that dominate the PA market today. ParkerVision expects to be shipping its own branded products that incorporate our digital power amplifier chips by end of this year."

D2D Technology
Extending the science behind its patented Direct2Data(TM) (D2D(TM)) digital RF transceiver technology into power amplifiers, the new products target product applications that are forecasted to consume nearly one and a half billion RF power amplifiers this year and would continue to grow at up to 18% unit volumes year over year - according to a report by Allied Business Intelligence (ABI). RF power amplifiers are a critical component of all wireless RF devices used in digital communications. They boost the transmitted RF signal so that it can reach its intended destination. The transmitter in these devices is commonly the single largest power consumer oftentimes accounting for the majority of all power used by a wireless RF product. While traditional RF power amplifiers are built from legacy analog circuits with inherent efficiency and performance limitations, ParkerVision's digital RF power amplifiers benefit from the only 100% digital architecture. ParkerVision's power amplifiers reduce total transmitter power consumption by 50% to 80%.

Parker continued, "Our expertise in high performance digital architectures allowed us to create an ultra-efficient all digital power amplifier technology. The excellent linearity of our proprietary technology makes it applicable to all wireless RF digital communications, even challenging applications such as CDMA or OFDM used in higher data rate Wi-Fi applications.

ParkerVision to Exit Retail Operations and Focus as an OEM Supplier of Integrated Circuits for Wireless Devices (June 28, 2005)
ParkerVision, Inc. (Nasdaq NMS: PRKR), announced today that it is exiting its retail business activities and plans to continue its pursuit of an OEM business strategy as a pure-play fabless semiconductor company. Exiting the retail business is expected to reduce the company's cash utilization rate by approximately 25%-35% going forward and would also require taking charges to the company's second quarter operating results. The company has estimated the total charge to be between $4.5 and $5.7 million of which approximately $3.8 to $5.0 million are non-cash. The nature of the charges includes impairment to inventory and other retail assets, staff reduction, and other related charges.

Jeffrey L. Parker, the Chief Executive Officer of ParkerVision commented, "Based on feedback we've received from both consumers and retailers alike, our retail strategy was successful in achieving an important goal for the company - namely, proving that our digital wireless technology brought the benefits to consumer products that we predicted, and establishing the reliability of our D2D(TM) technology. From a financial standpoint, however, the chasm between showcasing the benefits of our technology in finished products to creating shareholder value in a retail model can only be bridged by making significant additional investment in brand awareness campaigns, retail channel expansion, inventory commitments and human resources. We believe to make such an investment in capital and resources at this time would severely detract from our ability to capitalize on the OEM opportunities that are now within our reach. We also believe that these OEM opportunities provide a much better leverage point for attaining significant revenue growth, favorable product margins and profitability for our shareholders.

"Our new digital ultra-efficient power amplifiers, which we call Direct-to-RF-Power(TM) (D2P), have been extremely well received by the OEM community. The interest from our OEM prospects has reached a level where we believe it is clear that the greatest shareholder value can be achieved in the least amount of time by exclusively pursuing OEM opportunities as aggressively as possible and becoming a significant component supplier to OEMs that build high volume wireless products. Our initial D2P IC designs are applicable to battery powered, portable wireless devices such as cellular phones, wireless networking devices, cordless phones and Bluetooth devices. The preliminary success of our D2P initiative has also resulted in a renewal of interest by OEM prospects in our original D2D based ICs. We believe our product development efforts for the retail market would ultimately be leveraged through our product offerings to OEMs.

"We are very appreciative of the contributions by our employees, distributors, retailers, and other partners who have supported our retail efforts and we would work with our current retail partners over the next several weeks to execute on our retail exit strategy in a controlled and equitable manner," concluded Parker.
