SGB-2233 Datasheet, PDF (1/6 Pages) List of Unclassifed Manufacturers – DC-4.5GHz Active Bias Gain Block
Product Description
Sirenza Microdevices’ SGB-2233 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 3V to 5V supply
the SGB-2233 does not require a drop resistor as com-
pared 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 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.
