SGB-6433 Datasheet, PDF (1/6 Pages) List of Unclassifed Manufacturers – DC-3.5 GHz Active Bias Gain Block

Product Description
Sirenza Microdevices’ SGB-6433 is a high performance
SiGe HBT MMIC amplifier utilizing a Darlington configura-
tion 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
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 applications 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.
