www.DataSheet4U.com Preliminary Product 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 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 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 50Ω nominal RF input impedance. A single external output matching circuit covers the entire 4.95.9GHz band simultaneously. The external output match allows for load line optimization for other applications or optimized performance over narrower bands.
