SBB4089Z Datasheet | RF Micro Devices

50MHz to 6000MHz CASCADABLE ACTIVE BIAS In Ga P HBT MMIC AMPLIFIER Package: SOT-89 Product Description RFMD’s SBB4089Z is a high performance In Ga P 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 pared to typical Darlington amplifiers. The SBB4089Z product is designed for high linearity 5V gain block applications that require small size and minimal external ponents. It is internally matched to 50s.
