Description

NEC's MC-7845, MC-7846, and MC-7847 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, 22 dB, and 25 dB respectively.

Because these units are GaAs MC-7847 they have low distortion, low noise figure, and low return loss across the entire frequency band.

Like the previous generation of products, MC-7847 survive 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 of MC-7847 performance, and reliability is assured by NEC's stringent quality and process control procedures. These parts come in industry compatible hybrid packages.
