In an image suppression receiver which is employed in such as a heterodyne receiver, the inter-signal errors between the I signal and the Q signal becomes the noise of the image signal frequency components, and thereby the communication quality is deteriorated. In such a wireless communication device, a high performance image suppression circuit is realized. There are provided two image suppression circuits 6-1, 6-2, and in the one hand image suppression circuit 6-1, the I signal and the Q signal are replaced and the desired wave signal is recognized as an image signal and is suppressed, and on the other image suppression receiver 6-2, it is recognized as a desired wave signal and is made pass through without occurring losses, and the phases and the amplitudes of the I signal and the Q signal are adjusted by the IQ signal adjustment circuit so that the ratio between the outputs of the respective image suppression circuits 6-1, 6-2 become the maximum. Thus, a high performance image suppression receiver can be realized.
