WJ Communications Introduces High Performance 28V InGaP HBT Power Amplifier Technology for Mobile Infrastructure Applications

Posted on: Tuesday, 6 June 2006, 09:00 CDT

WJ Communications, Inc. (NASDAQ: WJCI), a leading designer and supplier of RF solutions for the

wireless infrastructure and RFID reader markets, today announced it has developed an exciting new 28V InGaP HBT technology for mobile infrastructure power amplifier applications. This technology provides significant advantages in power output and efficiency compared to other technologies currently on the market. This 28V process was developed from our existing 5V InGaP HBT process that has been proven to be a very high reliability process ideally suited for mobile infrastructure applications. Several new products using the new 28V process are currently in development and will be released in the third quarter of 2006.

"We are very excited about the development of this new 28V InGaP HBT process. It offers significantly improved ACPR/ACLR performance at equivalent or higher efficiencies than LDMOS products that are currently on the market," said Morteza Saidi, vice president of engineering for WJ Communications. "Units can be operated as Class B amplifiers and still achieve very low ACPR/ACLR performance as the result of unique circuit design techniques (patent pending). Initially we are planning to introduce several products up to 10W P1dB; this technology is suitable for products with higher power as well."

Process Overview

The +28V InGaP HBT process is state-of-the art with exceptional breakdown voltage and power handling capabilities. Lifetime tests have already been run for over 4000 hours at 315 C junction temperature with minimal beta degradation. The process has also proven to be capable of handling up to 6 dB overdrive on the input without failure.

Package Development

WJ Communications has also developed a new surface mountable power QFN package for these InGaP HBT products that incorporates a eutectic die attach for the semiconductor die to minimize thermal resistance and ensure highly reliable operation.

A whitepaper on this topic will be available via the WJ corporate web page on Thursday, June 15th, 2006 at the following URL: http://www.wj.com/.
