SZA-2044

SZA-2044(Z) SZA-2044(Z) 700MHz to 2.7GHz 5V 1W Power Amplifier 700MHz to 2.7GHz 5V 1W Power Amplifier Package: QFN, 4mm x 4mm Product Description Features RFMD’s SZA-2044 is a high efficiency 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 specifically designed as a final stage 802.11b/g and 802.16 equipment in the 2.0GHz to 2.7GHz bands. It can run from a 3V to 5V supply. Optimized on-chip impedance matching circuitry provides a 50 nominal RF input impedance. The external output match and bias adjustability allows load line optimization for other applications over narrower bands, It features an output power detector, Optimum Technology on/off power control, and high RF overdrive robustness. This Matching® Applied product is available in a ROHS Compliant and Green package GaAs HBT with matte tin finish, designated by the “Z” package suffix.
