Abstract

PURPOSE:To attain the antenna sharing at an adjoining transmitting/receiving area, by providing two pairs of filters having an LPF and an HPF between a transmission terminal and a reception terminal and switching the antenna and simultaneously, the set of filters. CONSTITUTION:A transmission terminal 7 is connected through a transmission terminal switch 1 and through a transmission LPF2 or a transmission HPF3 to an antenna terminal switch 9. In the same way, a reception terminal 8 is connected through a receiving terminal switch 10 and through a reception LPF4 or a reception HPF5 to an antenna terminal switch 9. An antenna terminal switch 9 is connected to an antenna 6 for transmission and reception. The HPF and LPF of the transmission and reception are changed-over by switches 1, 9 and 10. Thus, an antenna sharing at an adjoining transmitting/receiving band is realized.
