A phase compressor for a phase modulated signal comprises n phase suppressors (n is an integer greater than 2) each of which includes an adder and a limiter. The n phase suppressors are connected in series with one another. In this case, outputs from the limiters of nth (n - 1)th (n - 2)th, .... 2nd phase suppressors are individually supplied to the adders along with outputs from the (n - 1)th (n - 2)th, .... 1st phase suppressors, respectively. A reference signal generator is connected to the adder associated with the nth phase suppressor so that the angular, range of the phase-modulated signal at the circuit output terminal is phase-compressed by 1/(n+1) compared to the angular range of …
