  • Selective peak limiter with a circulator having a third branch having band-pass filter, a threshold element and an adapted load in series
    Patent number: 6374087
    Abstract: A peak limiter is intended to limit the peak of a signal that has a given frequency, in an assembly comprising other signals of lower amplitude and different frequencies. The peak limiter includes a circulator inserted into a line transporting all the signals. A first branch of the circulator is connected to a line on its upstream side. Its second branch is connected to a line on its downstream side. It's third branch is connected to a reference terminal via the combination of a band-pass filter centered on the given frequency, a threshold element, and an adapted load connected in series.
