1 / 3 page NEC's 870 MHz GaAs CATV PUSH-PULL AMPLIFIER MC-7831 MC-7832 MC-7833 OUTLINE DIMENSIONS (Units in mm) PACKAGE OUTLINE H02 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.
