SBB1089Z
50MHz to 850MHz,
CASCADABLE
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 5V supply, the SBB1089Z does
not require a dropping resistor as compared to typical Darlington amplifi-
ers. The SBB1089Z product is designed for high linearity 5V gain block
applications that require small size and minimal external components. It is
internally matched to 50.

Pin Function Description
1RF 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.
3RF 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.
