RFMD SBB Gain Blocks ® 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.
