Anadigics launches linear PA for AWS and KPCS CDMA/EVDO mobile equipment

Anadigics Inc of Warren, NJ, USA has launched the AWT6309 linear power amplifier (PA), for use specifically in CDMA wireless handsets and data devices that operate in 1.7GHz bands. The new PA is designed to be compatible with Qualcomm CDMA2000 and EVDO chipsets.

The newest member of Anadigics’ family of HELP2 CDMA power amplifiers, the AWT6309 reduces average current consumption by as much as 50% compared to conventional two-stage amplifiers thanks to Anadigics’ proprietary designs and InGaP-Plus HBT technology (which integrates switches and amplifier components onto the same die).

Measuring 3mm x 3mm by 1mm high in a low-profile surface-mount package, AWT6309 enables the design of ultra-slim and compact products, Anadigics says. In addition, the new PA also integrates an internal voltage regulator that eliminates the need for external voltage regulators.

Specific features include: high efficiency of 41% at +28dBm output and 22% at +17dBm; a low quiescent current of 14mA; and a low leakage current in shutdown mode of less than 1 microAmp.

“With the introduction of the AWT6309 power amplifier, Anadigics is prepared for the expansion of CDMA services in the AWS band here in the US and in the KPCS band in Korea,” says Ali Khatibzadeh, senior VP and General Manager of Wireless Products.
