PURPOSE:To easily fix parts by including a microwave circuit constituted of microstrip lines in a circuit constituted of triplate type strip lines. CONSTITUTION:A part of the 1st dielectric base 1 and the 1st ground conductor plate 4 is removed, the microwave circuit 7 constituted on the 3rd dielectric substrate 12 is formed on the surface of the 2nd dielectric substrate 3 from which the substrate 1 and the plate 4 are partially removed, the strip conductors 2a, 2b formed on the I/O terminal of the circuit 7 are connected to the strip conductors of the triplate type strip lines 11, 13, and then the lines 11, 13 between the 1st and 2nd ground conductors 4, 5 are mutually connected through conductors 10 in the vicinity of the connection part of the strip conductors 2a. Thereby, all currents flowing into the lines 11, 13 can be inputted/outputted to/from the circuit 7 without being reflected. Thus, the microwave circuit 7 can be individually produced and the fixing of parts can easily be executed. |
