RMBA09501A-58
Cellular 2 Watt Linear GaAs MMIC Power
Amplifier
ADVANCED INFORMATION
Description
The RMBA09501A-58 is a high power, highly linear Power Amplifier. The two stage circuit uses Raytheon’s pHEMT
process. It is designed for use as a driver stage for Cellular base stations, or as the output stage for Micro- and
Pico-Cell base stations. The amplifier has been optimized for high linearity requirements for CDMA operation. The
device is matched for 50 ohms input impedance.

Notes:
1. Only under quiescent conditions - no RF supplied.
2. 50 ohm system, Vdd = 7.0V, Tc = 25°C.
3. 9 Channel Forward Link QPSK Source; 1.23 Mbps modulation rate. ACPR1 measured at 885 KHz offset at a value ≥ 37 dBc. CDMA
Waveform measured using the ratio of the average power within the 1.23 MHz channel and within a 30 kHz bandwidth at an 885 MHz offset.
4. Ultra-linear OIP3 specifications are achieved for power output levels of 27 and 30 dBm per tone.
5. Gate Voltage can be adjusted to optimize the linearity of the amplifier for differing modulation systems. Default biasing is optimized for
CDMA (Ref. Note 3).
Characteristic performance data and specifications are subject to change without notice.
