摘要： The invention relates to a tunable resonator filter. In each resonator cavity of the filter there is a movable dielectric tuning element (728; 748) to adjust the resonator's natural frequency. The tuning elements are advantageously arranged to be moved by a common control implemented by a rod (708) joining them together, to shift the filter's band through equal displacements of the natural frequencies of the resonators. When the tuning element is moved horizontally sidewards from the resonator (710; 720; 730; 740; 750; 760) axis, the electrical length and natural frequency of the resonator change. In that case, when sub-bands are used it is not necessary to tune the filters separately for each sub-band in the stage of manufacture, as the sub-band can be chosen when the filter is put into use. The tuning elements can be movable also in each resonator separately, to implement the basic tuning in connection with the manufacture of the filter. The basic tuning can be automated, in other words it can be made without inconvenient handwork.

摘要： An adjustable resonator filter (200), the operating band of which can be shifted by a one-time adjustment. The natural frequency of each resonator (210, 220) is affected, in addition to the basic tuning arrangement, by an adjustment circuit (ACI), which includes a fixed tuning element (280) in the resonator cavity and an adjusting part (290) outside the cavity. The tuning element has an electromagnetic coupling to the basic structure of the resonator. The adjustment circuit is functionally a short transmission line, which is “seen” by the resonator as a reactance of a certain value. By changing the electric length of the transmission line, the value of the reactance and the electric length and natural frequency of the whole resonator are changed. The change is implemented in the adjustment part by means of switches or a movable dielectric piece. In the resonator filter each resonator has a similar adjustment circuit, and the adjustment circuits have common control (CNT) for shifting the band of the filter. When the subband division is in use, the filters need not be separately adjusted for each subband in connection with the manufacture. No moving parts are required inside the filter housing.

摘要： A small in-band-flat-group-delay type dielectric filter having low-loss characteristics with a small amplitude deviation and uniform-group-delay frequency characteristics is obtained, which enables broad-band characteristics to be obtained easily. The in-band-flat-group-delay type dielectric filter includes a plurality of dielectric coaxial resonators, a coupling circuit comprising a combination of reactive elements, with which the dielectric coaxial resonators are coupled to one another, and input/output terminals connected to ends of the coupling circuit. The dielectric coaxial resonators coupled to the input/output terminals are allowed to have a different characteristic impedance from that of the inter-stage dielectric coaxial resonators.

摘要： A sharp-cutoff VHF elliptic filter includes a folded signal path and internally coupled feedback in a conductive enclosure. Sized for the power requirements of commercial television broadcast transmission, the filter implements the elliptic filter equation through use of cavities, resonators, and couplers. The negative feedback required by the elliptic filter equation is implemented by folding the RF signal path and coupling the feedback energy through a gap in an internal septum to sum negatively with the signal in the main signal path. The elliptic filter can have an interdigital configuration, which puts successive resonators on opposite walls of the enclosure and couples the signal at half-wavelength spacing. The elliptic filter can alternatively have a comb line configuration, which places all resonators on one wall and employs full-wavelength spacing.
