Product Description

Features

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

over narrower bands, It features an output power detector,
