Product Description  
Features  
RFMD’s SZA-3044 is a high linearity 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 spe-  
cifically designed as a final or driver stage for 802.16 equipment in the 3.3GHz to  
3.8GHz bands. It can run from a 3V to 6V supply. Optimized on-chip impedance  
matching circuitry provides a 50nominal RF input impedance. The external out-  
put match and bias adjustability allows load line optimization for other applications  
or over narrower bands. It features an output power detector,

VPC1 is the bias control pin for the stage 1 active bias circuit. An external series resistor is required for proper setting of  
bias levels. Refer to the evaluation board schematic for resistor value. To prevent potential damage, do not apply voltage  
to this pin that is +1V greater than voltage applied to pin 20 (Vbias) unless Vpc supply current capability is less than  
10mA.
