PERFORMANCE
• HIGH RELIABILITY AND RUGGEDNESS:
Withstands environmental extremes as well as Silicon
devices (Surge, ESD, Etc.)
DESCRIPTION
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.
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.
