Product Description
RFMD’s CGB-1089Z is a high performance InGaP HBT MMIC amplifier uti-
lizing a Darlington configuration with a 75Ω 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 CGB-1089Z
does not require a dropping resistor as compared to typical Darlington
amplifiers. The CGB-1089Z product is designed for high linearity 5V gain
block applications that require small size and minimal external compo-
nents. It is internally matched to 75Ω.
