The MC-7852 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 18 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 assembled and
tested using fully automated equipment to maximize the consistency in part to part performance. The MC-7852G features
round connection pins and slightly different body dimensions
for customers desiring these packaging dimensions.
