RMPA0913C-58
3.5V AMPS/CDMA Power Amplifier
Description
Features
The RMPA0913C-58 is a monolithic high efficiency power amplifier for AMPS/
CDMA dual mode applications in the 824 to 849 MHz frequency band.
Performance parameters may be slightly adjusted by “tweaking” off-chip
matching components. The amplifier circuit design is a single ended
configuration that utilizes harmonic tuning for increased power added efficiency
and linearity. The device uses Raytheon’s Pseudomorphic High Electron
Mobility Transistor (pHEMT) process.
Positive supply voltage of 3.5V, nominal
Power Added Efficiency of 56%, typical, at power out of 31.5 dBm
Power Added Efficiency of 40%, typical, for CDMA power out of 28.5 dBm

Notes:
1. Source/Load VSWR (All Angles) ≤ 3:1 In-Band, Load VSWR (All Angles) ≥ 20:1 Out of
Band, Valid over Case Operating Temperature Range.
2. Po ≤ 28.5 dBm at Vdd=3.5V; CDMA Waveform measured using the ratio of the average
power within a 1.23 MHz channel and within a 30 kHz bandwidth at the specified offset.
3. Vg1 adjusted for Idq (stage 1) = 35 mA, Vg2 adjusted for Idq (stage 2) = 155 mA.
