CGR-0118Z

DUAL CATV 5MHz to 65MHz CATV AMP IC

RFMD’s CGR-0118Z is a high performance 75

 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

75

 return path applications where linear performance is needed over

the frequency range 5MHz to 65MHz.
