摘要： An object of the present invention is to provide a resonator capable of constituting a variable filter which has a small size, high mass productivity, low loss and high reproducibility of frequency. According to the present invention, a resonator having a line structure formed on a dielectric substrate 2, is reduced in size by providing a counter electrode 6 in the direction perpendicular to a surface of a resonant line 4 for forming a capacitive reactance which is added to the resonance circuit. The resonator can be further reduced in size by providing widened parts 7a, 7b on the resonant line with the use of the skin effect of an electric signal propagating in the resonant line, so as to enable a large capacitive reactance to be obtained, and by providing the widened parts and the counter electrodes for a part on the resonant line where a magnitude of voltage standing wave is high.

摘要： A multiband matching circuit includes a first matching unit, a second matching unit, and a third matching unit, with all units being connected in series in a signal path. Matching with target impedance is established at a first frequency by appropriately designing the first matching unit and at a second frequency by appropriately designing the second and third matching units. The second matching unit and the third matching unit are designed to make the conversion ratio of the impedance viewed from the connection point between the second matching unit and the third matching unit to a circuit element to the target impedance smaller than the conversion ratio of the impedance viewed from the connection point between the first matching unit and the second matching unit to the circuit element to the target impedance, at the second frequency.
