Abstract

PURPOSE:To reduce the cross modulation distortion of a broadband width signal by interposing a phase-frequency characteristic equalizer between a non-linearity compensator and power amplifier. CONSTITUTION:As for frequency characteristics of amplitude and a phase between non-linear distortion occurrence points of non-linearity compensator 1 and power amplifier 4, amplitude characteristic equalizer 2 and phase characteristic equalizer 3 and used in a fixed band to flatten the amplitude characteristic and to make the phase linear to the frequency by compensating. Therefore, the response of the compensation relation between non-linearity compensator 1 and power amplifier 4 improves and cross modulation distortion can be reduced effectively.
