<p><P>PROBLEM TO BE SOLVED: To provide a transmitter and a transmitter-receiver which transmit signals of plural radio bands while suppressing occurrence of a higher harmonic wave and intermodulation distortion. <P>SOLUTION: The transmitter which transmits the signals of plural radio frequency bands comprises: a signal generation part which generates signals of a band 1 to a band N (N is an integer of 2 or more); a distortion compensation part for reducing the higher harmonic wave of the signal generated by the signal generation part and the intermodulation distortion occurring between the signals of the band 1 to the band N; a DAC part which converts a digital signal outputted from the distortion compensation part to an analog signal; and an amplifier which amplifies a multiband signal of a radio band. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
