RM805
Power Amplifier Module for Broadband
The RM805 Power Amplifier (PA) is a fully matched 28-pin surface mount module
designed for Private Mobile Radio (PMR), Wireless Local Loop (WLL), and Time
Division Multiple Access/Advanced Mobile Phone Service (TDMA/AMPS) mobile units
operating in the 806-849 MHz cellular bandwidth. Microwave Monolithic Integrated
Circuits (MMICs), comprised of Gallium Arsenide (GaAs) and CMOS, contain all active
circuitry in the module, which includes on-board bias circuitry as well as input and
interstage matching circuits. The output match is realized off-chip within the module
package to optimize efficiency and high power performance (P

load.
This device, manufactured with Skyworks鈥?GaAs Heterojunction Bipolar Transistor
(HBT) and silicon CMOS processes, provides for all positive voltage DC supply
operation while maintaining high efficiency and good linearity. Primary bias to the
RM805 can be supplied directly from a single cell lithium-ion or other suitable battery
with a nominal output 3.5 Volts.
No external supply side switch is needed as typical 鈥渙ff鈥?leakage is a few
microamperes with full primary voltage supplied from the battery.
