DESCRIPTION

10.75 ±0.25

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

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

MHz. This unit has a minimum gain of 21.5 dB at 860 MHz,

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.
