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.

Pin Function Description
1 RFFB Feedback pin. External DC-blocking capacitor is required.
2RFIN
RF input pin. External DC-blocking capacitor is required.
3RFIN
Same as pin 2.
4 RFFB Same as pin 1.
5RFOUT
RF output and bias pin (open collector).
6,7 BYPASS AC ground/Bypass.
8RFOUT
Same as pin 5.
EPAD GND Exposed area on the bottom side of the package must be soldered to the ground plane of hte board for optimum
thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended
land pattern.
Important Power Supply Note
The bias circuits used in 12V and 8V applications allow lower overall power consumption but can suffer
damage from power supplies with fast turn-on times. To avoid the possibliity of damaging the IC with supplies
which ramp faster than 1ms, we recommend slowing the ramp by adding a series resistor and parallel
capacitor on the Vdd line. This is not a requirement at 5V operation.
