SGC4486Z

SGC4486Z 50MHz to 4000 MHz Active Bias Silicon Germanium Cascadable Gain Block SGC4486Z 50MHz to 4000MHz ACTIVE BIAS SILICON GERMANIUM CASCADABLE GAIN BLOCK Package: SOT-86 Product Description RFMD’s SGC4486Z is a high performance SiGe HBT MMIC amplifier utilizing 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 SGC4486Z does not require a dropping resistor as compared to typical Darlington amplifiers. The SGC4486Z is designed for high linearity 3V gain block applications that require small size and minimal external components. It is internally matched to 50Ω.
