RMPA0913C-58
3.5V AMPS/CDMA Power Amplifier
PRODUCT INFORMATION
Description
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.

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.
Characteristic performance data and specifications are subject to change without notice.
