Product Description
Sirenza Microdevices鈥?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 specifically 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 imped-
ance matching circuitry provides a 50鈩?nominal RF input
impedance. The external output match and bias adjustabil-
ity 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.
