PERFORMANCE
HIGH RELIABILITY AND RUGGEDNESS:
Withstands environmental extremes as well as Silicon
devices (Surge, ESD, Etc.)
DESCRIPTION
NEC's MC-7845, MC-7846, and MC-7847 are GaAs Multi-
Chip Modules designed for use as output stages in CATV ap-
plications up to 870 MH
z
. The only difference between these
devices is gain, which is 18 dB, 22 dB, and 25 dB respec-
tively. Because these units are GaAs devices they have 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 performance, and reliability is assured by NEC's strin-
gent quality and process control procedures. These parts come
in industry compatible hybrid packages.
