ABSTRACT:
A signal switching apparatus for switching between a 1/4 wavelength transmission line, which transmits a transmission signal, and a 1/4 wavelength reception line, which receives a reception signal, which share a common antenna. The apparatus sets the characteristic impedance of one of the 1/4 wavelength lines to be zero while the other 1/4 wavelength lines is set to infinity so that the switching operation can be effected without passing the transmission and reception signals through semiconductor switches.
