ANADIGICS Launches Linear Power Amplifiers for AWS, KPCS CDMA/EVDO Mobile Equipment

(Product News, 3 Apr 2008)

ANADIGICS Inc.'s new AWT6309 linear power amplifier is designed specifically for use in CDMA wireless handsets and data devices that operate in 1.7GHz bands. Compatible with Qualcomm CDMA2000 and EVDO chipsets, ANADIGICS' AWT6309—the newest member of its HELP2 CDMA Power Amplifiers family—reduces average current consumption as much as 50 percent compared to conventional two-stage amplifiers.

The new amplifier's power saving feature is the result of ANADIGICS' proprietary designs and unique InGaP-Plus technology, which integrates switches and amplifier components onto the same die thus enabling creative new architectures and solutions for product designers and engineers. Measuring 3x3x1mm, the AWT6309 enables designers to create ultra slim and compact products. In addition, the new device also integrates an internal voltage regulator that eliminates the need for external voltage regulators.

Specific features of ANADIGICS' new AWT6309 include:
- High efficiency: 41 percent at +28dBm output; 22 percent at +17dBm output
- Low quiescent current: 14mA
- Low leakage current in shutdown mode: <1µA
