Product Description
SGB-6433
Sirenza Microdevices’ SGB-6433 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 temper-
ature and process Beta variations. Designed to run directly from a 5V
supply the SGB-6433 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-6433 product is designed for high linearity 5V 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.
