RFMD’s SGB2400 is a high performance Darlington SiGe HBT MMIC amplifier with on-chip active bias circuitry. The active bias network provides stable current over temperature and process Beta variations. The SGB2400 is designed to operate directly from a 3V supply. The SGB2400 product is designed for high linearity 3V gain block applications that require small size and minimal external components. The die is internally matched to 50Ω.
