<p>An antenna sharer uses a dielectric filter (11) at a transmission side and a SAW filter (12) at a reception side. Interference of the reception side filter to the transmission side filter due to use of different types of filters is adjusted by a phase adjuster (16). This minimizes power loss of a transmission signal and lowering of reception sensitivity. That is, the transmission power loss is reduced by phase adjustment by the phase adjuster (16) and lowering of the reception sensitivity is reduced by using only the SAW filter at the reception side.</p> |
