MC-7881
NEC's 870 MHz GaAs CATV MC-7882
POWER DOUBLER AMPLIFIER MC-7883
MC-7884
FEATURES
• GaAs ACTIVE DEVICES
• LOW DISTORTION
• HIGH LINEAR GAIN:
MC-7881 - GL = 18 dB MIN at f = 870 MHz
MC-7882 - GL = 20 dB MIN at f = 870 MHz
MC-7883 - GL = 22 dB MIN at f = 870 MHz
MC-7884 - GL = 25 dB MIN at f = 870 MHz
LOW RETURN LOSS
LOW GAIN CHANGE OVER TEMPERATURE
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-7881, MC-7882, MC-7883, and MC-7884 are GaAs
Multi-Chip Modules designed for use as output stages in CATV
applications up to 870 MHz. The only difference between these
devices is gain, which is 18 dB, 20 dB, 22 dB, and 25 dB
respectively. 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.
