详细描述The SZA-5044 is a high efficiency 4.9-5.9 GHz class AB Heterojunction Bipolar Transistor (HBT) power amplifier housed in a low-cost surface mountable plastic package. This HBT amplifier is made with InGaP on GaAs device technology and is fabricated with MOCVD for an ideal combination of low cost and high reliability. This device is specifically designed as a final or driver stage for 802.11a equipment in the 4.9-5.9 GHz 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 4.9-5.9 GHz 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.特点P1dB = 29 dBmSimultaneous 4.9 - 5.9 GHz performanceOutput Return Loss < -11 dBOn chip output power detector802.11a Pout = 21.5 dBm @ 3% EVMSingle Supply Voltage = 5V
