Power Amplifier for CDMA Handsets

This RF power amplifier (RMPA0965) is optimized for CDMA2000-1X applications in the
824 to 849 frequency band. It has single positive-supply operation, low power and shutdown modes, and provides 40% CDMA mode efficiency at 28 dBm average power output. Its high/low power modes optimize battery talk-time and reduce current consumption during peak phone usage. The two-stage power amplifier is matched to 50 W (input and output) minimizing the need for external components. The high power-added efficiency (PAE) and linearity is due to a proprietary InGaP heterojunction bipolar transistor (HBT) process. Package size is 3 ¥ 3 mm.
