SZA-5044Z数据手册Qorvo中文资料规格书

描述 Description

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.
