50MHz to 6000MHz CASCADABLE ACTIVE BIAS InGaP HBT MMIC AMPLIFIER
Package: SOT-89
Product Description
RFMD’s SBB4089Z 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 Beta variations. Designed to run directly from a 5V supply, the SBB4089Z does not require a dropping resistor as compared to typical Darlington amplifiers. The SBB4089Z product is designed for high linearity 5V gain block applications that require small size and minimal external components. It is internally matched to 50s.
