Product Description
Features
RFMD’s SGC-6489Z is a high performance SiGe HBT MMIC amplifier utiliz-  Single Supply Operation: 5V
ing a Darlington configuration with an active bias network. The active bias at ID = 85mA
network provides stable current over temperature and process Beta varia-
tions. Designed to run directly from a 5V supply, the SGC-6489Z does not
require a dropping resistor as compared to traditional Darlington amplifi-
ers. The SGC-6489Z product is designed for high linearity 5V gain block
S applications that require small size and minimal external components. It is
internally matched to 50.
