SZA-2044(Z)
700MHz to 2.7GHz 5V 1W Power Amplifier
Package: QFN, 4mm x 4mm
Product Description
RFMD’s SZA-2044 is a high efficiency class AB heterojunction bipolar transistor
(HBT) amplifier housed in a low-cost surface-mountable plastic package. This HBT
amplifier is made with InGaP on GaAs device technology and fabricated with
MOCVD for an ideal combination of low cost and high reliability. This product is spe-
cifically designed as a final stage 802.11b/g and 802.16 equipment in the 2.0GHz
to 2.7GHz bands. It can run from a 3V to 5V supply. Optimized on-chip impedance
matching circuitry provides a 50 nominal RF input impedance. The external out-
put match and bias adjustability allows load line optimization for other applications
Optimum Technology

GaAs HBT
over narrower bands, It features an output power detector,
on/off power control, and high RF overdrive robustness. This
product is available in a ROHS Compliant and Green package
with matte tin finish, designated by the “Z” package suffix.
