RFMD’s SZM-2166Z is a high linearity class AB Heterojunction Bipolar Transistor (HBT) amplifier
housed in a low-cost surface-mountable plastic Q-FlexN multi-chip module 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 for
802.16 customer premises equipment (CPE) terminals in the 2.3GHz to 2.7GHz bands. It can
run from a 3V to 6V supply. The external output match and bias adjustability allows load line
optimization for other applications over narrower bands. It features an output power detector,
on/off power control, and high RF overdrive robustness. A 20dB step attenuator feature can be
utilized by switching the second stage Power up/down control. This product features a RoHS
compliant and Green package with matte finish, designated by the “Z” suffix
