Anadigics ships PAs for Sierra Wireless’ COMPASS 885 USB Modem

Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AWT6155, AWT6221 and AWT6241 power amplifiers (PAs) to Sierra Wireless for use in the Compass 885 USB Modem, which features a compact USB design and microSD slot that offers high-speed connectivity for both Mac and Windows notebook and desktop computers on HSUPA networks. The Compass 885 USB modem is compatible with 3G networks worldwide.

“We are pleased to have been selected for Sierra Wireless’ 885 USB modem for notebooks and desktop computers,” said Ali Khatibzadeh, senior vice president & general manager of Wireless business at Anadigics. " Anadigics is well positioned to capture 3G market share by leveraging our advanced technology to provide customers with higher performing EDGE and WCDMA power amplifiers."

The AWT6155 is a quad-band polar EDGE PA module in 5mm x 5mm package that is half the size of the previous generation PA modules, thereby reducing RF board area in dual-, tri- and quad-band designs. Designed specifically for 3G mobile products, the AWT6155 has two amplifier chains, one to support GSM850/900 bands and the other for DCS/PCS bands. Each amplifier chain is optimized for greater efficiency, power, and linearity in a polar loop environment while maintaining high efficiency in GSM/GPRS mode.

The AWT6221 and AWT6241 are both members of Anadigics’ WCDMA PA family and incorporate the firm’s' HELP3 technology to provide low power consumption without the need for an external voltage regulator. The dual-band AWT6221 combines North American cellular and PCS bands in a 3mm x 5mm package, while conserving printed-circuit board area through the integration of two independent PA chains. Anadigics’ AWT6241 PA is designed for WCDMA/HSPA wireless handsets and data-card applications in the IMT band, and provides low power consumption without the need for an external voltage regulator or DC/DC converter, adds the firm.
