摘要： A filter and a method of making a filter to remove unwanted frequency harmonics associated with current filters. The filter is made up of resonators, such that the filter resonates a design frequency. Whereby, at least two resonators are coupled together between an input and an output and at least one of the resonators is of a different design from other resonators, such that the resonator of a different design resonates the same design frequency as the other resonators and resonates different higher order harmonic frequencies than the other resonators. The present invention also provides methods of improving skirt response for a filter, as well as other response properties of the filter.

摘要： A dielectric filter having excellent spurious suppression characteristics is disclosed. To avoid degradation of filtering characteristics caused by generation of spurious radiation, namely, high-level unwanted resonance oscillation in the passing band at the same frequency as that used for a mobile telephone in a microwave range, at least two types of dielectric resonators are combined and arranged in spaces separated by a partition wall inside a shielded body comprising a metal case and a metal cover, wherein the resonators have mutually different frequency characteristics in an unwanted harmonic mode other than the main mode in the vicinity of the passing band of the filter.

摘要： The invention relates to an half-wave resonator providing reduced second armonic spurious mode, the resonator comprises a λ/2-length microstrip conductor, where λ is the line wavelength correspondent to the fundamental resonance frequency and is characterized in that it further comprises means for forcing a low voltage in the middle of the λ/2-length microstrip conductor. Advantageously, such means for forcing a low voltage comprise a low impedance, wide-band resistor. The invention further includes a band filter and a method for providing reduced second armonic spurious mode in a half-wave resonator.

摘要： The harmonic multiples of the operating frequency of a dielectric filter are attenuated by a non-conducting pattern, which is formed on one (19) or more side faces of a housing block (12) which are otherwise coated with a conducting material. The pattern may consist of linear areas (20,22), the optimum width of which is approximately 1 mm.

摘要： A strip-type second-harmonic-choking filter is constituted such that a main transmission line (2), through which a fundamental frequency wave is to be transmitted, is connected with a first stub (4) which exhibits a first susceptance value for the fundamental frequency and exhibits a subtantially infinite admittance value for a second harmonics of the fundamental frequency, on a side of said main transmission line (2); and a second stub (5) which exhibits a second susceptance value which is essentially conjugate of the first susceptance value for the fundamental frequency and exhibits an infinity or zero admittance value for the second harmonic frequency, at an opposite side of the transmission line (2) from the first stub (4). For the fundamental frequency wave, the two stubs (4, 5) cancel the effects of each other so that no effect is given on the transmission of the fundamental wave, while one or both of the stubs choke(s) the transmission of the second-harmonic wave. The stub may be bent so that more area is easily available for circuits to be installed on the same circuit board.

摘要： An extremely narrow-band bandpass electromagnetic filter comprises a waveguide (1) dimensioned below cutoff and having two or more active sections (30) each containing a dieletric resonator (6). The number of resonators (6) corresponds to the number of poles of filtering. The physical dimensions of the waveguide (1) can advantageously be further reduced by means of passive coupling means (40), where the waveguide (1) cross-section is smaller than in the active sections (30). Each passive coupling means (40) inductively couples adjacent active sections (30). Mode suppression rods (10) electrically connect opposing waveguide walls (2, 3) midway between each pair of adjacent dielectric resonators (6). Preferred embodiments are illustrated, in which the resonators (6) are transversely oriented within the waveguide (1). Electromagnetic energy travels within the waveguide (1) in a single TE10 evanescent mode (TE01 delta within the resonators (6)). Dielectric tuning means (9) are generally aligned along the principal axis of each resonator (6). A number of such filters, exhibiting extremely narrow bandwidth, low insertion loss, and high Q, have been successfully built.
