LPA Module For CDMA Measures Just 4 mm Square

Designed for transmit functions in CDMA2K 1X cellular, multi-mode data enabled handsets, Model CHP0205-QM linear power amplifier (LPA) module measures just 4 x 4 x 1.5 mm. The module is fabricated using an InGAP HBT technology, said to deliver low thermal resistance and reliable electrical stability. It operates over a 824 to 849 MHz frequency range and delivers a 36% linear power efficiency and +28 dBm of output power. Other features include 50_ internal impedance matching and a dc power-down mode. A test fixture is also available. CELERITEK, INC., Santa Clara, CA. (408) 986-5060.
