Abstract
A high frequency video isolation circuit comprising: a modulating signal source for producing a modulating signal having a frequency of several hundred megahertz; an input multiplier for multiplying the modulating signal with an input video signal having frequency components in a frequency range from about several hertz to about one hundred or more megahertz, to produce a modulated video signal having frequency components in a frequency range from about one hundred megahertz to about several hundred megahertz; a first isolation transformer having an input and an output, for transforming the modulated video signal from the input to the output; and an output multiplier for multiplying the transformed modulated video signal with the modulating signal to produce an isolated output video signal having the frequency components of the input video signal.
