Dual Band WCDMA Power Amplifier Module
1850 to 1910 MHz and 1920 to 1980 MHz
General Description
The RMPA2265 power amplifier module (PAM) is designed
for WCDMA applications in both the 18501910 and 1920
1980 MHz bands. The 2 stage PAM is internally matched to
50
to minimize the use of external components and
features a low-power mode to reduce standby current and
DC power consumption during peak phone usage. High
power-added efficiency and excellent linearity are achieved
using Fairchild's InGaP/GaAs Heterojunction Bipolar
Transistor (HBT) process.
Features
Single positive-supply operation and low power and
shutdown modes
42% WCDMA efficiency at +28 dBm average output
power 19201980 MHz
39% WCDMA efficiency at 27.5 dBm average output
power 18501910 MHz
Meets UMTS/WCDMA performance requirements in
both UMTS bands
Compact, low-profile package(3.0 x 3.0 x 1.0 mm
nominal)
Internally matched to 50
and DC blocked RF input/
output
