Product Description
Sirenza Microdevices鈥?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 50惟 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, designated by the 鈥淶鈥?package
suffix.
