Package: QFN, 4mmx4mm
Product Description
RFMD’s SZA-5044 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 or driver stage for 802.11a equipment in the
4.9GHzto5.9GHz band for a 5V supply. Optimized on-chip impedance matching cir-
cuitry provides a 50Ω nominal RF input impedance. A single external output match-
ing circuit covers the entire 4.9GHzto5.9GHz band simultaneously. The external
output match allows for load line optimization for other appli-

cations or optimized performance over narrower bands. This
product is available in a RoHS Compliant and Green package
