    Qorvo's SZA-5044 is a high efficiency 4.9GHz to 5.9GHz class AB Heterojunction Bipolar Transistor (HBT) power amplifier housed in a low-cost surface mountable plastic package. This HBT amplifier designed as a final or driver stage for 802.11a equipment in the 4.9GHz to 5.9GHz band, operating from a 5V supply. Optimized on-chip impedance matching circuitry provides a 50 ohm nominal RF input impedance. A single external output matching circuit covers the entire 4.9GHz to 5.9GHz band  simultaneously. The external RF output match and bias adjustability allows load line optimization for other applications or optimized performance over other bands. It features an output power detector, on/off power control, and high RF overdrive robustness.
