Title: ParkerVision Receives Patent for its Core D2D Receiver Technology
Date: 5/9/2000; Publication: PR Newswire;
Unique Architecture Contravenes Traditional RF Engineering;
Allows for Smaller, More Reliable Radios With Less Power Consumption

 

JACKSONVILLE, Fla., May 9 /PRNewswire/ –
ParkerVision, Inc. (Nasdaq: PRKR) received U.S. Patent 6,061,551 covering the fundamentals of its Direct2Data™ (D2D™) 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, headquartered in Jacksonville, Florida, designs, develops and manufactures communications technology platforms and products for the wireless and video industries. Additional information about ParkerVision and its D2D technology is available at www.parkervision.com and www.D2D.com.
