Abstract
A signal selecting circuit comprises a first switch means connected between a first input terminal and a common output terminal, a second switch means connected between a second input terminal and the common output terminal, a first microstrip line for connecting the first switch means and the common output terminal, and a second microstrip line for connecting the second switch means and the common output terminal, wherein a length of the first microstrip line is set to be approximately odd-numbered times of 1/4 wavelength of a frequency of an image signal relative to the second mode reception signal, and a length of the second microstrip line is set to be approximately odd-numbered times of 1/4 wavelength of a frequency of an image signal relative to the first mode reception signal.
