Abstract

PURPOSE:To reduce cross modulation, by providing a means which generates components opposite to cross modulation components in the transmission side and by controlling this means in the receiving side. CONSTITUTION:Outputs of transmitters 3 and 4 having frequency components f1 and f2 are radiated from an antenna 13 through circulators 7 and 8. In this case, a frequency of cross modulation distortion is generated in the transmission signal on a signal transmission line. A part of this cross modulation distortion signal is received by a receiver 16. A detection signal generated outside the band of the base band signal is inputted to a control circuit 27, and frequency components generated by a mixer 28 are controlled by the output of the circuit 27. Consequently, cross modulation distortion is reduced.
