DESCRIPTION

NECs 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.

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.)

APPLICATIONS

• CATV HEADEND SYSTEMS

• CATV OPTICAL NODES

• CATV DISTRIBUTION AMPS
