RFMD’s STA-6033 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 specifically designed as a final stage for 802.11a equipment in
the 4.9 GHz to 5.9GHz band. It can be run from a 3V to 6V supply. Optimized on-chip imped-
ance matching circuitry provides a 50 nominal RF input impedance. A single external output
allows for matching circuit covers the entire 4.9GHz to 5.9GHz band. The external output
match allows for load line optimization for other applications or optimized for other applications
or optimized performance over narrower bands. It is designed as a drop in replacement for sim-
ilar parts in its class. This product is available in RoHS Compliant and Green package with
matte tin finish, designated by the “Z” package suffix.
