Warren, N.J. — Anadigics, Inc. has introduced a family of HELP (High-Efficiency-at-Low-Power) CDMA linear power amplifier modules. The new AWT6137 AMPS/CDMA and AWT6138 PCS/CDMA PA modules deliver DC power consumption along with footprint compatibility with the previous generation of products.

The HELP PA modules take advantage of novel and proprietary techniques to reduce handset power consumption by 50%, delivering an efficiency of 20% at +16 dBm, compared with 8% to 10% for currently available products. The devices' unique design uses mode switching to take advantage of high-efficiency operation over a wide range of output powers. At +28 dBm, the AWT6137 and AWT6138 provide an efficiency of 39%. Both of the new PAs provide low leakage currents in shutdown mode of less than 1 muA, and the AWT6137 offers an idle current of 15 mA at +28 dBm. The AWT6137 and AWT6138 support CDMA 1XRTT and 1xEV-DO operation.

"Anadigics' HELP PAs use the prevailing industry standard 4 mm x 4 mm module footprint and control logic," said Dr. Ali Khatibzadeh, vice president of Wireless Products at Anadigics, Inc. "These features enable customers to take advantage of the enhanced performance and cost provided by our HELP PAs without any change to their phone board designs or significant software revisions."

Future HELP PA products will include variants for the Korean and Japanese domestic markets as well as for WCDMA applications. The AWT6137 and AWT6138 power amplifiers are priced at $2.95 in quantities of 10,000 units. For more information, visit www.anadigics.com.
