Dual-band CDMA Power Amplifiers
Anadigicsannounces a family of dual-band InGaP power amplifiers (PAs) supporting the AMPS/cellular and PCS frequency bands. The PAs provide full compliance with CDMA 1xRTT and CDMA 1xEV-DO standards, high efficiency, and desirable linearity to enable impressive signal integrity for mobile data applications. The 3 × 5 mm AWT6310 and AWT6314 feature independent RF paths to ensure optimal performance in both frequency bands. The modules feature 39% efficiency, 50 mA of quiescent current, and 1µA of leakage current in both bands, resulting in good talk-time and standby-time for today’s power-hungry multimedia handsets. The PA modules deliver 27.5 dB gain in the cellular band and 26.5 dB gain in the PCS band, and offer a typical adjacent channel power of approximately 50 dBc in both bands. The dual-band CDMA power amplifiers are designed for applications that require European Union’s RoHS products.
