RFMD’s SZA-3044 is a high linearity 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 or driver stage for 802.16 equipment in the 3.3GHz to
3.8GHz bands. It can run from a 3V to 6V 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
or over narrower bands. It features an output power detector,
Optimum Technology
on/off power control and high RF overdrive robustness. This
Matching® Applied
product is available in a RoHS Compliant and Green package
