SGC4263Z

50MHz to 4000MHz ACTIVE BIAS SILICON

GERMANIUM CASCADABLE GAIN BLOCK

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

.
