Qorvo's STA-6033 is a high performance, high efficiency 4.9-5.9 GHz Class AB Heterojunction Bipolar Transistor (HBT) power amplifier housed in a low cost surface mountable QFN 3x3 plastic package. This device is designed as a final stage for 802.11a equipment in the 4.9-5.9 GHz band. It can operate from a 3.0 to 3.6V supply. Optimized on-chip impedance matching circuitry provides a 50 ohm nominal RF input impedance. A single external output matching circuit covers the entire 4.9-5.9 GHz band. The external output match allows for load line optimization for other applications, or optimized performance over narrower bands. The STA-6033 is designed as a drop-in replacement for similar parts in its class.
