PURPOSE:To eliminate the need for a coupling circuit, and to reduce size by forming a cable path where a cable is to pass in the thickness part of a wall member which costitutes an external housing, and also installing a cable for composition in the wall member of the external housing. CONSTITUTION:A metallic external housing 9 consists of a bottom plate 91, front and rear side walls 92 and 93, left and right end-part side walls 94 and 95, a center partition wall 96, and a cover plate 97. Inside of the external housing 9, a filter Ft for transmission is incorporated in one chamber of the partition wall 96, and a filter Fr for reception is incorporated in the other chamber. The filters Ft and Fr each have plural resonating elements 10 to form multistage resonators. The output terminal To and input terminal Ti of both the filters Ft and Fr are connected to an antenna respectively, and connected to the antenna terminal of the cover plate 94 through composite cables Ct and Cr. |
