DESCRIPTION

The MC-7856 is a GaAs hybrid integrated circuit designed to

be used as the input device in CATV applications up to 860

and because it is a GaAs device, it has lower distortion and

lower noise figure. Reliability is assured by NEC's stringent

quality and process control procedures. Devices are as-

sembled and tested using fully automated equipment to maxi-

mize the consistency in part to part performance. The MC-

7856G features round connection pins and slightly different

body dimensions for customers desiring these packaging di-

mensions.
