PROBLEM TO BE SOLVED: To solve the problem of a conventional front end distortion compensator circuit that cannot cancel an intermodulation distortion component generated by an amplifier. SOLUTION: This front end distortion compensator circuit is provided with an input terminal 101 that receives a prescribed signal, a diode 106 as a nonlinear element connected directly to the input terminal 101, a bias supply circuit consisting of a resistor 104, a power terminal 103 and a capacitor 105 to apply a voltage to the diode 106, specific frequency suppression means 108, 109 that are directly connected across the diode 106 not through any other element and suppress part of or all frequencies from a frequency equivalent to DC up to a frequency equivalent to an occupied bandwidth of the input signal received at the input terminal 101 and/or at least one harmonic frequency of the carrier of the input signal and an output terminal 102 that outputs a signal.
