Product Description
Sirenza Microdevices’ CGB-1089Z is a high performance InGaP HBT MMIC
amplifier utilizing a Darlington configuration with a 75 ohm 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
components. It is internally matched to 75 ohms.
