Title: ParkerVision Receives Patent For Its Core D2D Transmitter Technology
Date: 7/18/2000; Publication: PR Newswire;
Unique Transmitter Architecture Applicable to Wide Range of Wireless Applications

 

JACKSONVILLE, Fla., July 18 /PRNewswire/ –
ParkerVision, Inc. (Nasdaq: PRKR) received U.S. Patent 6,091,940, covering the fundamentals of its Direct2Data™ (D2D™) direct conversion radio transmitter 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 940 patent issued by the United States Patent & Trademark Office contains 374 claims and cites over 600 references. It is part of ParkerVision’s overall intellectual property strategy, which includes more than 70 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) transmitter architecture that provides efficient direct up-conversion in a single step from baseband information to a modulated on-channel RF carrier. The company’s unique Direct2Data (D2D) transmitter architecture reduces the cost, power, and parts count by eliminating all the Intermediate Frequency (IF) components required in traditional widely deployed heterodyne-based transmitters. As with ParkerVision’s Direct2Data receiver architecture, the D2D transmitter should enable high levels of integration in all semiconductor processes including standard CMOS.

 

Jeffrey Parker, Chairman and Chief Executive Officer, stated, “The architecture protected by this patent further positions ParkerVision to capitalize on the commercial potential of its D2D technology. We continue to believe D2D will have a dramatic impact on the wireless industry in terms of product enhancement and cost and power savings. Securing patent protection helps to reinforce our commercialization efforts as we continue the process of building shareholder value.”
David F. Sorrells, Chief Technical Officer and lead inventor of the technology, stated, “The 940 patent is another important milestone for ParkerVision. It affirms the D2D technology for use in RF filters, receivers, and transmitters, which represent all of the basic building blocks of radio transceivers, both wireless and wired.”

 

ParkerVision, headquartered in Jacksonville, Florida, designs, develops and manufactures communication 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.
