Abstract:
A high-frequency switching module including a switching circuit and a filtering circuit, comprising:a multi-layer assembly having a plurality of dielectric sheets of layers placed one over another; a plurality of high-frequency terminals provided on outer surfaces of the multi-layer assembly; said switching circuit formed in the layers of said multi-layer assembly having a first end thereof connected to a first high-frequency terminal of said plurality of high-frequency terminals; and said filtering circuit formed in the layers of said multi-layer assembly having a first end thereof connected to a second end of said switching circuit, a second end thereof being connected to a second high-frequency terminal of said plurality of high-frequency terminals, wherein said plurality of high-frequency terminals are provided on a mounting side surface of said multi-layer assembly while lateral sides of said multi-layer assembly are not provided with any electrode for said high-frequency terminals, said multi-layer assembly having a rectangular four-sided outer shape and connection terminals provided at an inner region of the mounting side surface for external connection reinforcement, the connection terminals being positioned in symmetry with respect to substantially a center of the mounting side surface of the multi-layer assembly.
