The distortion compensating circuit for an electrooptic converter includes a secondary distortion generating circuit 12, an amplitude vs. frequency characteristic compensating circuit 16 provided at an output coupling of the secondary distortion generating circuit, a distributing directional coupler 14 for distributing an RF signal provided at a previous stage of the secondary distortion generating circuit, a tertiary distortion generating circuit 13 provided at a coupling port of the distributing directional coupler, an amplitude vs. frequency characteristic compensating circuit 26 provided at a posterior stage of the tertiary distortion generating circuit, a phase vs. frequency characteristic compensating delay line 16 for a signal on the secondary distortion generating circuit side and a signal on the tertiary distortion generating circuit side, and a mixing directional coupler 15 for mixing the signal on the secondary distortion generating circuit side and the signal on the tertiary distortion generating circuit side.
