Title: ParkerVision Receives Sixth Wireless Patent
Date: 3/5/2002; Publication: PR Newswire;

 

JACKSONVILLE, Fla. – ParkerVision, Inc. announced today it has received its sixth U.S. patent for its unique Direct2Data(TM) wireless technology. The patent covers some of the fundamentals of the Direct2Data transmitter technology where in a single unified operation an on-channel RF carrier is achieved in a direct up-conversion from a baseband information signal. Patent #6,353,735 details a sub-harmonically controlled aperture architecture that enables high performance direct conversion transmitters that can be implemented in CMOS, the most commonly available and least expensive silicon semiconductor process.

 

U.S. Patent 6,353,735 issued to ParkerVision by the United States Patent & Trademark Office contains 33 claims and cites over 600 references. “Combining this patent with our already issued and pending receiver patents broadens ParkerVision’s intellectual property portfolio to include complete Direct2Data based direct conversion transceivers,” stated David Sorrells, Chief Technical Officer.

 

This patent further strengthens the company’s intellectual property position. The company is aggressively pursuing the protection of its RF technology and has more than 80 additional patents pending and continues to file additional protection related to its wireless technology. ParkerVision is also pursuing the development of complete RF transceiver ICs built on the foundation of the Direct2Data technology. The first products the Company is readying for commercial availability are for wireless LAN (WLAN) 802.11b with subsequent products for 802.11g, 802.11a, and the cellular/PCS standard CDMA 2000 - 1X.

 

ParkerVision, headquartered in Jacksonville, Florida, designs, develops and manufactures communications technology platforms and products for the wireless and video industries. The video division is engaged in the design, development and marketing of automated video camera control systems and automated live production systems for broadcasting and webcasting.

 

ParkerVision is a leader in direct conversion radio technology. Its patented D2D(TM) radio communications technology enables the development of advanced, highly integrated products for a wide range of wireless and wired radio-based devices. D2D’s innovative RF technology simplifies wireless electronics, resulting in smaller, cost-effective, high-performance wireless communications products.
