RI23110
CDMA PCS 3–4 Volt Power Amplifier (1720–1910 MHz)
The RI23110 Personal Communications Service (PCS) Power Amplifier is a fully
matched 6-pin LCC surface mount module developed for PCS and wireless local
loop applications. This small and efficient Power Amplifier packs a full 1720–1910
MHz bandwidth coverage into a single compact package. This device meets the
stringent spectral linearity requirements of Code Division Multiple Access (CDMA)
PCS transmission, with high power added efficiency for power output of up to 29
dBm. A single GaAs Microwave Monolithic Intergrated 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 within
the module package to optimize efficiency and power performance into a 50
Ω
load.
This device is manufactured with Skyworks’ GaAs HBT process that provides for all
positive voltage DC supply operation while maintaining high efficiency and good
linearity. Primary bias to the RI23110 is 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.
