Description
Absolute Maximum Ratings
The AP119-89 is a low cost IC power amplifier designed
for the 1700–1900 MHz frequency band. It features 3.5 V
battery operation, and exceptional efficiency.
The AP119-89 is designed to be stable over a
temperature range of -40 to +85°C and over a 10:1 output
VSWR load. External matching is used for improved
performance, flexibility, and multi-band operation.

Output Matching Circuit
The output match for the AP119-89 is provided externally
in order to improve performance, reduce cost, and add
flexibility. By making use of ceramic surface mount
components with better Qs than GaAs matching
elements, a lower loss matching network can be made.
This lower loss results in higher power and efficiency for
the amplifier. Also, by keeping these elements external the
GaAs die size is reduced and the overall cost is less.This
approach also permits the flexibility to tweak the amplifier
for optimum performance at different powers, and/or
frequencies.
