Product Description
Features
RFMD’s CGR-0118Z is a high performance 75Ω push-pull InGaP HBT
MMIC amplifier utilizing a Darlington configuration with an active bias net-
work. The active bias netwrok provides stable current over temperature
and process variations. Designed to run over a wide range of supply volt-
age, from 5V to 12V, the CGR-0118Z does not require a bias resistor as
compared to typical Darlington amplifiers. The CGR-0118Z is designed for
75Ω return path applications where linear performance is needed over
the frequency range 5MHz to 65MHz.
