摘要： A substrate (1) is used as one tube wall (12) of a hollow waveguide (11), the substrate (1) including a strip line (2) wired in an inner layer, a first ground surface (3) formed on a front surface, and a second ground surface (4) formed on a part of a back surface. As a result of such a configuration, a waveguide strip line transducer having the same dimension as the external dimension of the hollow waveguide (11) can be obtained.

摘要： A surface mount high-frequency circuit is configured such that a plurality of ground pads 41 and a plurality of external connection ground conductors 51 are discretely disposed to surround a signal line pad 42 and an external connection signal line conductor 52, and a plurality of interlayer connection ground conductors 31 and that a plurality of columnar ground conductors 12 are discretely disposed to surround an interlayer connection signal line conductor 32. Thus, it is possible to suppress radiation of an unnecessary signal to the outside using a simple production process that is completed by only a wafer process without separately preparing a component such as a shield cover case.

摘要： In cases where a power divider is constructed by using a multilayer substrate, a power divider is obtained which is smaller in size and has a good reflection property. The power divider according to the present invention is provided with a multilayer dielectric substrate (1), strip conductor patterns (2a through 2c) formed on one surface of the multilayer dielectric substrate (1), and a ground conductor pattern (3) formed on the other surface of the multilayer dielectric substrate (1), wherein a transmission line is composed of the dielectric substrate (1), the strip conductor patterns (2a through 2c) and the ground conductor pattern (3), and the transmission line has its one end branched to form a plurality of branch lines (12a, 12b), with an isolation resistance (4) being formed between the branch lines. A first capacitance forming part comprising a first pillar conductor (6a) and a first capacitance forming conductor pattern (5a), both formed in an interior of the dielectric substrate (1), is formed at a branch point (13) of said transmission line.
