摘要： A center conductor having a length L1, which is equivalent in electrical length to one quarter wavelength, and ground conductors disposed on the opposite sides of the center conductor with a gap portion therebetween in coplanar manner are formed on a dielectric substrate. The center conductor and the ground conductors located on the opposite sides thereof, and are connected together by shorting ends. This results in the formation of corner areas, respectively, whereby obtaining a coplanar waveguide resonator. An edge line of the shorting end is recessed to have a curve configuration so that each corner area has an angle greater than 90 degrees, which reduces power current concentration at the corner points in the respective corner areas.

摘要： A plurality of one-quarter wavelength coplanar resonators 5a to 5d are formed in series on a dielectric substrate 1, and coplanar input/output terminal sections 4a and 4b are formed on the dielectric substrate at opposite ends of the series connection for coupling with resonators 5a and 5d, respectively. A center conductor line width w1 of each of the resonators 5a to 5d is equal to a center conductor line width wio of each of the input/output terminal section 4a and 4b, but a ground conductor spacing d1 of each of the resonators 5a to 5d is greater than a ground conductor spacing dio of each of input/output terminal section 4a and 4b. Maintaining the accuracy of design is facilitated and a reduction in the maximum current density in the resonator is enabled.

摘要： A filter is provided which maintains a low insertion loss characteristic of a filter contained in a casing with a very simple construction that the internal wall of the casing is formed by a superconductor. A coplanar waveguide filter 22 comprises a dielectric substrate 1, a plurality of resonators 5a, 5b, 5c and 5d and input/output terminal sections 4a and 4b, each of which is formed by a center conductor 2 and ground conductors 3a and 3b, both formed on the same surface of the dielectric substrate 1, with the ground conductors 3a to 3d being formed on the opposite sides of and in parallel relationship with the center conductor 2. The filter 22 is contained within a casing 21 having an internal wall, the surface of which is formed with a layer of superconductor 23. By way of example, a high temperature superconductor such as lanthanum-, yttrium-, bismuth- or thallium-superconductor is deposited as a film on a substrate of a metal oxide material such as MgO, SrTiO3, LaGaO3, LaAlO3 to provide a superconductor filmed substrate 25, which is applied to the internal surface of the casing 21. Electromagnetic power which is irradiated from the filter 22 does not produce a power loss when it impinges on the layer of superconductor 23 in its superconducting state, but is reflected therefrom to be absorbed by the filter 22, thus reducing the filter insertion loss.

摘要： A transmission signal containing signals of a plurality of frequency bands is divided and fed to a linear signal transfer path including a delay circuit and a plurality of distortion generation paths for the plurality of frequency bands. In each distortion generation path, the signal of the corresponding frequency band is extracted by a band signal extractor from the signal fed to the path, an odd-order distortion of the extracted signal is generated by an odd-order distortion generator, and the phase and amplitude of the odd-order distortion are adjusted by a vector adjuster to provide the output signal of the distortion generation path. The output signals from such plurality of distortion generation paths are combined by a combiner with the output from the linear signal transfer path to provide the combined output as the output from a multi-band predistorter using power series representation.
