• SPECIFIED FOR 79, 110, and 132 CHANNELS

PERFORMANCE

• HIGH RELIABILITY AND RUGGEDNESS:

Withstands environmental extremes as well as Silicon

devices (Surge, ESD, Etc.)

DESCRIPTION

NEC's MC-7831-HA is a GaAs Multi-Chip Module designed

cause this unit is a GaAs device, it has low distortion, low noise

figure, and low return loss across the entire frequency band.

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 NEC's stringent quality

and process control procedures. These parts come in industry

compatible hybrid packages.
