RM807
Power Amplifier Module for TDMA PCS (18501910 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 18501910 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 34 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.
