Description

Sirenza Microdevices' SZA-5044 is a high efficiency class AB Heterojunction Bipolar Transistor (HBT) amplifier housed in a low-cost surface-mountable plastic package. This HBT amplifier SZA-5044 is made with InGaP on GaAs device technology and fabricated with MOCVD for an ideal combination of low cost and high reliability.

SZA-5044 is specifically designed as a final stage for 802.11a equipment in the 4.9 - 5.9 GHz band for a 5V supply. Optimized on-chip impedance matching circuitry provides a 50 nominal RF input impedance. A single external output matching circuit covers the entire 4.9- 5.9GHz band simultaneously. The external output of SZA-5044 match allows for load line optimization for other applications or optimized performance over narrower bands.
