Product Description
Sirenza Microdevices’ SZA-2044 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 combi-
nation of low cost and high reliability. This product is specif-
ically designed as a final stage for 802.11b/g and 801.16
equipment in the 2.0-2.7 GHz bands. It can run from a 3V to
5V supply. Optimized on-chip impedance matching circuitry
provides a 50Ω nominal RF input impedance. The external
output match and bias adjustability allows load line optimi-
zation for other applications or over narrower bands. It fea-
tures 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,
designated by the “Z” package suffix.
