Product Description

Sirenza Microdevices’ SGC-4486Z 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 SGC-4486Z does not require a dropping resistor as compared to typical Darlington amplifiers. The SGC-4486Z is designed for high linearity 3V gain block applications that require small size and minimal external components. It is internally matched to 50 ohms.
