Abstract
To obtain a uniform improving effect of secondary distortion over a wide frequency band with a very simple configuration and less power consumption in the distortion compensation circuit, that improves the secondary distortion circuit of an optical transmitter and a high-frequency amplifier used for a transmission line processing a high-frequency signal over a wide frequency band, such as a cable television(CATV). A fundamental passing path for passing a fundamental wave is configured by connecting an attenuation component 102 for attenuating a signal, comprising a combination of resistors in series with a delay line 103, and a distortion adding path to add distortion is configured by connecting a 1st attenuation component 104 for attenuating a signal comprising a resistor, a 1st diode 105 and a 2nd diode 106 for generating distortion in series and connecting a 2nd delay element 107 and a 2nd attenuation element 108 for setting a signal level and comprising a resistor is series between a connecting point Q of the 1st diode 105 and the 2nd diode 106 and an output terminal 109.
