RFMD Green, RoHS Compliant, Pb-Free (Z Part Number)
Package: 3x3 QFN, 16-Pin
Product Description
RFMD’s SGB-2433 is a high performance SiGe HBT MMIC amplifier utilizing a Dar-
lington 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 3Vto5V supply the SGB-2433 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-2433 prod-
uct is designed for high linearity 3V gain block applications that require small size
and minimal external components. It is on chip matched to 50Ω and an external
bias inductor choke is required for the application band.
