Product Description
Features
RFMD’s SGC4363Z is a high performance SiGe HBT MMIC amplifier utiliz-
ing a Darlington configuration with a patented active bias network. The
active bias network provides stable current over temperature and process
Beta variations. Designed to run directly from a 3V supply, the SGC4363Z
does not require a dropping resistor as compared to typical Darlington
amplifiers. The SGC4363Z is designed for high linearity 3V gain block
applications that require small size and minimal external components. It is
internally matched to 50.
