PURPOSE:To improve the positioning precision of input and output terminals and to reduce the manhoure of components and assembly by forming integrally a case and other end of the input/output terminal to a frame and arranging one end of the terminal to an input output section of electronic components. CONSTITUTION:A case main body 2, input/output terminals 18, and an antenna terminal 19 are formed integrally to a frame 15 formed by blanking one metallic plate, and a carrier hole 15a of the frame 15 is set to a carrier machine. While the main body 2 is being carried, a connection base 6, a low pass filter board 7 and a stray board 8 are placed to the main body 2. On terminal 18b of both the input/output terminals 18 and one terminal 19b of the antenna terminal 19 are placed to electrodes 12, 13, C5, C8 of the boards 6-8. A coupling board 4 is arranged to an upper side of the board 6, coils L1-L4 and chip capacitors C9-C11 are arranged to the upper side of the boards 7, 8, dielectric coaxial resonators R1-R4 at the RX side and resonators R5-R7 at the TX side are arranged in parallel on a low wall 2a of the main body 2, and a coupling terminal 5 is abutted on the capacitor electrodes C1-C4, C9-C11. |
