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
