The RMBA19500A-58 is a high power, highly linear Power Amplifier. The circuit uses Raytheon's pHEMT process. It has been designed for use as a driver stage for PCS1900 base stations, or as the output stage for Micro- and Pico-Cell base stations. The amplifier has been optimized for high linearity requirements for PCS operation. The device is matched for 50 ohms input impedance. 2 Watt linear output power at 38 dBc ACPR1 for CDMA operation OIP3 43 dBm at 27 and 30 dBm output Small Signal Gain of 28 dB
