Sirenza Microdevices’ SGB-2233 is a high performance SiGe HBT
MMIC amplifier utilizing a Darlington configuration with an active bias
network. The active bias network provides stable current over tempera-
ture and process Beta variations. Designed to run directly from a 3V to
5V supply the SGB-2233 does not require a drop resistor as compared
to typical Darlington amplifiers. This robust amplifier features a Class
1C ESD rating, low thermal resistance , and unconditional stability. The
SGB-2233 product is designed for high linearity 3V gain block applica-
tions that require small size and minimal external components. It is on
chip matched to 50 ohm and an external bias inductor choke is required
for the application band.
This product is available in a RoHS Compliant and Green package with
matte tin finish, designated by the “Z” package suffix.
