RM807
Power Amplifier Module for TDMA PCS (1850–1910 MHz)
The RM807 Power Amplifier Module (PAM) for Personal Communications Service
(PCS) is a fully matched 6-pin surface mount module developed for PCS and wireless
local loop applications. This small and efficient power amplifier packs a full
1850–1910 MHz bandwidth coverage into a single compact package. This device
meets the stringent spectral linearity requirements of Time Division Multiple Access
(TDMA) PCS transmission with high power added efficiency to output power of
29.5 dBm. A single Gallium Arsenide (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 with Skyworks’ GaAs
Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage
DC supply operation while maintaining high efficiency and good linearity. Primary bias
to the RM807 can be supplied directly from a three-cell nickel cadmium, single cell
lithium ion, or other suitable battery with output in the 3–4 volts 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.
