Product Description
Features
RFMD’s SBB3000 is a high performance InGaP HBT MMIC amplifier utiliz-
ing a Darlington configuration with an active bias network. The active bias
network provides stable current over temperature and process Beta varia-
tions. The SBB3000 product is designed for high linearity 5V gain block
applications that require excellent gain flatness, small size, and minimal
external components. It is internally matched to 50.
