Power Amplifier Module for AMPS Applications (824–849 MHz)
The RM914 Advanced Mobile Phone Service (AMPS) Power Amplifier is a fully
matched 6-pin surface mount module designed for mobile units operating in the
824-849 MHz cellular bandwidth. This device can be driven to power output levels
beyond 31 dBm for high efficiency FM mode operation. A single GaAs Microwave
Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The
MMIC contains on-board bias circuitry as well as input and interstage matching
circuits. The output match is realized off-chip and within the module package to
optimize efficiency and power performance into a 50
load. This device is
manufactured with Skyworks’s GaAs HBT process that provides for all positive
voltage DC supply operation while maintaining high efficiency. Primary bias to the
RM914 can be supplied directly from a three cell nickel-cadmium, single cell
lithium-ion, or other suitable battery with output in the 3-4 volt range. Power down is
accomplished by setting the voltage on the low current reference pin to zero volts. No
external supply side switch is needed as typical “off” leakage is a few microamperes
with full primary voltage supplied from the battery.
