DESCRIPTION
The MC-7866 is a GaAs hybrid integrated circuit designed to
be used as the output 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. These Power Doublers deliver these per-
formance advantages with 10 to 20% less DC input power.
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.
