50MHz to 3500MHz SILICON GERMANIUM ACTIVE BIAS GAIN BLOCK
Package: SOT-89
Product Description
RFMD’s SGC-6489Z is a high performance SiGe HBT MMIC amplifier utilizing a Darlington configuration with an active bias network. The active bias network provides stable current over temperature and process Beta variations. Designed to run directly from a 5V supply, the SGC-6489Z does not require a dropping resistor as compared to traditional Darlington amplifiers. The SGC-6489Z product is designed for high linearity 5V gain block applications that require small size and minimal external components. It is internally matched to 50.
