WJ Announces Amplifier Series For WiMAX/WiBro Applications

San Jose, CA -- WJ Communications, Inc. announced four products for WiMAX/WiBro applications. The new series includes AH314/AH315, high-linearity 2W 2-stage driver amplifiers, and AP561/AP562, high performance 8W single-stage power amplifiers. The AH314/AH315 products are readily available, while the AP561/AP562 will be available for sampling in January 2008 with production in March 2008.

These amplifiers are suitable for use in WiMAX/WiBro applications at the commonly targeted sub-bands within the 2.3 - 2.9 GHz and 3.3 - 3.8 GHz frequency ranges. All four amplifiers are based on the highly reliable InGaP/GaAs HBT process technology, and incorporate proprietary bias circuitry to compensate for variations in linearity and current draw over temperature. An internal active bias allows the AH314/5 to operate at single +5V, while the AP561/2 internal active bias allows them to operate at +12V with an added feature of a +5V power down control pin.

"The InGaP HBT process technology is fast becoming an industry standard especially for the next generation technologies. Our family of cost-optimized WiMAX products are highly reliable with exceptional linearity performance," said Morteza Saidi, Vice President of Engineering at WJ Communications. "The introduction of AH314/5 and AP561/2 reinforces our commitment to meet the requirements of the next generation wireless systems with high performance and cost-effective products."
