DESCRIPTION

10.75 0.25

NEC's MC-7847-KC is a GaAs Multi-Chip Modules designed

for use as output stages in CATV applications up to 870 MHz.

This is a high gain device offering 25 dB minimum gain at

870 MHz. Because this unit is a GaAs device it has low dis-

tortion, low noise ﬁgure, and low return loss across the entire

frequency band.

The MC-7847-KC is similar to NEC's standard push-pull

devices, but the higher current allows for better distortion

performance, especially X-mod.

APPLICATIONS

• CATV HEADEND SYSTEMS

• CATV OPTICAL NODES

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 performance, and reliability is assured by NEC's stringent

quality and process control procedures. These parts come in

industry compatible hybrid packages.
