CATV 22 dB PUSH-PULL AMPLIFIER MC-7856G
FEATURES
• GALLIUM ARSENIDE ACTIVE DEVICES
• LOW DISTORTION
• LOW NOISE FIGURE
(5.7 dB TYP at 860 MHz)
• HIGH RELIABILITY
(FIT = 125 at heat sink temperature of 100°C,
Report available)
• INDUSTRY COMPATIBLE PACKAGE
DESCRIPTION
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-
mizewww.DataSheet4U.com 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.
