50MHz to 4000MHz ACTIVE BIAS SILICON
GERMANIUM CASCADABLE GAIN BLOCK
Package: SOT-363
Product Description
RFMD’s SGC4263Z 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 SGC4263Z
does not require a dropping resistor as compared to typical Darlington
amplifiers. The SGC4263Z is designed for high linearity 3V gain block
applications that require small size and minimal external components. It is
internally matched to 50.
