SG850 is a high performance InGaP HBT MMIC amplifier utilizing a Darlington configuration with an active bias network.
The active bias network provides stable current over temperature and process Betavariations.
Designed to run directly from a 5V supply, the SG850 does not require a dropping resistor as compared to typical Darlington amplifiers.
The SG850 product is designed for high linearity 5V gain block applications that require small size and minimal external components.
