Gnd
NEC's MC-7831-HA is a GaAs Multi-Chip Module designed
for use as input stages in CATV applications up to 1 GH
z
. Be-
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.
