High Linearity InGaP HBT Active Bias Gain Block
The SBB series is a high-performance family of InGaP HBT MMIC amplifiers utilizing a Darlington configuration with an active bias
network. The active bias network provides stable current over temperature and process Beta variations. This product is designed for
high-linearity 5 V gain block applications that require excellent gain flatness, small size and minimal external components. Only two
DC blocking capacitors, a bias resistor and an RF choke are required for operation. The SBBs are internally matched to 50 ohms.
Applications for the SBB series include IF/RF amplifiers for WCDMA and TD-SCDMA basestations, and driver amplifiers for
cellular repeaters.
