Product Description
Sirenza Microdevices’ 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 specifically
designed as a final or driver stage for 802.16 equipment in
the 3.3-3.8 GHz bands. It can run from a 3V to 6V supply.
Optimized on-chip impedance matching circuitry provides a
50Ω nominal RF input impedance. The external output
match and bias adjustability allows load line optimization
for other applications or over narrower bands. It features an
output power detector, on/off power control and high RF
overdrive robustness. This product is available in a RoHS
Compliant and Green package with matte tin finish, desig-
nated by the “Z” package suffix.
