RM806
Power Amplifier Module for TDMA AMPS (824–849 MHz)
The dual-mode RM806 Power Amplifier (PA) is a fully matched, 6-pin, surface mount
module designed for Time Division Multiple Access (TDMA) and Advanced Mobile
Phone Service (AMPS) mobile units operating in the 824-849 MHz cellular bandwidth.
This device meets stringent IS-136 linearity requirements beyond 30 dBm output
power and can be driven to power output levels beyond 31 dBm for high efficiency FM
mode operation. A single GaAs (GaAs) Microwave Monolithic Integrated Circuit
(MMIC) contains all active circuitry in the module. The MMIC contains onboard 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 power
performance into a 50 ohm load. This device is manufactured using Skyworks’ GaAs
Heterojunction Bipolar Transistor (HBT) process, which provides for all positive
voltage DC supply operation while maintaining high efficiency and good linearity.
Primary bias to the RM806 can be supplied directly from a three-cell nickel cadmium,
a single-cell lithium-ion battery, or any other suitable battery with output in the
3 to 4 volts range. Power down is accomplished by setting 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.
