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 SZA-2044 technology and fabricated with MOCVD for an ideal combination of low cost and high reliability.  

SZA-2044 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 impedance matching circuitry provides a 50 nominal RF input impedance. The external output match and bias adjustability allows load line optimization for other applications or over narrower bands. SZA-2044 features an output power detector, on/off power control and high RF overdrive robustness.
