DESCRIPTION
The MC-7856 is a GaAs hybrid integrated circuit designed to
be used as the input device in CATV applications up to 860
MH
z
. 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. The MC-
7856G features round connection pins and slightly different
body dimensions for customers desiring these packaging di-
mensions.
