SGB2433Z
DC to 4GHZ ACTIVE BIAS GAIN BLOCK
RFMD Green, RoHS Compliant, Pb-Free (Z Part Number)
Package: 3x3 QFN, 16-Pin
Product Description
RFMD’s SGB2433Zis 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 SGB2433Z 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 SGB2433Z
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 and an exter-
nal bias inductor choke is required for the application band.
