NEC's 870 MHz GaAs CATV

PUSH-PULL AMPLIFIER

MC-7831

MC-7832

MC-7833

FEATURES

• GaAs ACTIVE DEVICES

• LOW DISTORTION

• HIGH LINEAR GAIN:

MC-7831 - GL = 18 dB MIN at f = 870 MHz

MC-7832 - GL = 22 dB MIN at f = 870 MHz

MC-7833 - 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-7831, MC-7832, and MC-7833 are GaAs Multi-

Chip Modules designed for use as input stages in CATV ap-

plications up to 870 MHz. 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.
