PAs feature 39% efficiency

Anadigics Inc. released a new family of dual-band InGaP power amplifiers (PAs) supporting the AMPS/cellular and PCS frequency bands. These new PAs provide full compliance with CDMA 1xRTT and CDMA 1xEV-DO standards, high efficiency, and excellent linearity to enable outstanding signal integrity for mobile data applications, said the press release. The small footprint 3-by-5-by-1mm AWT6310 and AWT6314 feature independent RF paths to ensure optimal performance in both frequency bands, while achieving a 25 percent space savings compared with solutions requiring two single-band PAs.

According to Dr. Ali Khatibzadeh, Senior Vice President and GM of Wireless Products at Anadigics, "Our new dual-band CDMA power amplifiers set a new industry benchmark in size, integration and performance."

The AWT6310 and AWT6314 PA modules feature 39 percent efficiency, 50mA of quiescent current and 1?A of leakage current in both bands, resulting in excellent talk-time and standby-time for today's power-hungry multimedia handsets. The PA modules deliver 27.5dB gain in the cellular band and 26.5dB gain in the PCS band, and offer an impressive typical adjacent channel power of approximately -50dBc in both bands to provide a high quality wireless connection for voice and data applications. The new family of dual-band CDMA PAs provides maximum PCB design flexibility to manufacturers by offering different pin-out configurations that simplify board layouts. Additionally, the company said, these PAs offer a common VMODE line to simplify the control interface and support single-mode operation up to full antenna power.

Both the AWT6310 and AWT6314 are priced at $2.50 in quantities of 10,000 units.
