RFMD’s CGA-7718Z is a high performance InGaP HBT MMIC Amplifier. Designed
with the InGaP process technology for excellent reliability. A Darlington configuration is utilized for broadband performance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. The CGA-7718Z
contains two amplifiers for use in wideband push-pull CATV amplifiers requiring
excellent second order performance. The second and third order non-linearities are
greatly improved in the push-pull configuration.

RF input pin. External DC-blocking capacitor is required.
Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as
possible.
Same as pin 1.
RF output and bias pin (open collector).
Same as pin 5.
Exposed area on the bottom side of the package must be soldered to the ground plane of the board for optimum
thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended
land pattern.
