摘要： A superconductor filter comprises a plurality of resonance elements arranged between input-output lines formed on a substrate. Metal conductor sections serving to inhibit the spatial coupling between the adjacent resonance elements are arranged between prescribed resonance elements, and a prescribed resonance element is coupled with another resonance element by a coupling transmission line. It follows that each resonance element is coupled with another resonance element by the direct coupling via the coupling transmission line or by the spatial coupling via the space.

摘要： There is disclosed a planar filter which can variably control a pass frequency band with a high precision and which is superior in skirt property and little in ripple. A planar filter member and tuning member are disposed opposite to each other via a predetermined gap. The filter member is structured in such a manner that an input/output portion formed of a superconductor and a plurality of resonance elements are formed on a substrate. The tuning member is structured in such a manner that on the surface of a magnetic plate with a permeability changing by an applied magnetic field, a plurality of dielectric thin films, and a plurality of electrodes for applying electric fields to the dielectric thin films are arranged. Each of the dielectric thin films is disposed in a position opposite to a gap between the resonance elements of the filter member, or a gap between the filter member and the input/output portion. By applying a voltage between the electrodes, an effective permittivity ∈ of the gap between the resonance elements, or the gap between the resonance element and the input/output portion is variably controlled, and the skirt property and ripple are adjusted. Moreover, a resonance frequency of the resonance elements, a coupling between the resonance elements, and a coupling between the resonance element and the input/output portion may be individually and independently controlled.

摘要： A filter circuit includes a first resonator and a second resonator each having a different resonance frequency. The first resonator is included in a first block, and the second resonator is included in a second block. The first block further includes a first delay unit connected to the first resonator. An input terminal divides an input signal to the first block and the second block. An output terminal combines signals passing through the first block and the second block and outputs the combined signal. The first delay unit converts a phase difference between the signals passing through the first block and the second block to reverse-phase or nearly reverse-phase.

摘要： In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state. In addition, a radio wave environment is measured. A characteristic necessary for the radio apparatus is determined corresponding to the measured radio wave environment. The power is controlled corresponding to the performance of the radio apparatus. Thus, the power consumption is decreased. In addition, the efficiency of the output power is improved. In the radio apparatus, the current consumption of a power amplifier PA is measured. A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss. In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave. When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process. In the radio apparatus, a transmission power detecting portion is structured as an IC chip. The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground. Thus, when the power is detected, a power loss is suppressed. Consequently, the power consumption of the radio apparatus can be decreased.

摘要： A heat insulating transmission line includes a first waveguide with a first aperture end, a second waveguide with a second aperture end, and a reflector. The second waveguide is arranged coaxially with the first waveguide. The second aperture end faces the first aperture end through an air gap. The reflector is provided outside the air gap, and controls radiation power from the air gap. In addition, the reflector is substantially parallel to a portion of a virtual plane connecting an inner wall of the first aperture end of the first waveguide and an inner wall of the second aperture end of the second waveguide. When a mean frequency of a signal transmitting through the heat insulating transmission line is expressed as λ, a distance between the virtual surface and the reflector is not less than N×λ/2−0.05λ and not more than N×λ/2+0.2λ (N is a positive integer).
