ACTIVE BIAS InGaP HBT MMIC AMPLIFIER
RFMD’s SBB1089Z 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 5 V supply, the SBB1089Z does
not require a dropping resistor as compared to typical Darlington amplifi-
ers. The SBB1089Z product is designed for high linearity 5 V gain block
applications that require small size and minimal external components. It is
internally matched to 50 .

Pin Function Description
1 RF IN RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation.
2, 4 GND Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possi-
ble.
3 RF OUT/BIAS RF output and bias pin. DC voltage is present on tis pin, therefore a DC blocking capacitor is necessary for proper opera-
tion.
