The MC-7834-KC is a GaAs Multi-Chip Module designed

for use as input stages in CATV applications up to 870 MH z .

Because this unit is a GaAs device, it has low distortion, low

noise ?gure, and low return loss across the entire frequency

band. The MC-7834-KC is similar to the standard push-pull

devices, but with the higher current allows better distortion

performance, especially X-Mod.

Like the previous generation of products, these devices sur-

vive such hazards as surge and ESD as well as their silicon

competitors, but deliver superior performance with low DC

current required.

All devices are assembled and tested using fully automated

equipment to maximize consistency in part to part perfor-

mance, and reliability is assured by stringent quality and

process control procedures. These parts come in industry

compatible hybrid packages.
