SBB2089Z Datasheet, PDF (1/7 Pages) RF Micro Devices – 50MHz to 850MHz, CASCADABLE ACTIVE BIAS InGaP HBT MMIC AMPLIFIER

SBB2089Z
50MHz to 850MHz, CASCADABLE
ACTIVE BIAS InGaP HBT MMIC AMPLIFIER
Package: SOT-89
Product Description
RFMD’s SBB2089Z is a high performance InGaP HBT MMIC amplifier uti-
lizing 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 SBB2089Z does
not require a dropping resistor as compared to typical Darlington amplifi-
ers. The SBB2089Z product is designed for high linearity 5V gain block
applications that require small size and minimal external components. It is
internally matched to 50.
