Abstract: A transverse magnetic (TM) mode dielectric filter includes an enclosure, a dielectric resonator, a main cover, and an elastic component, where the dielectric resonator is disposed in a resonant cavity of the enclosure; the main cover is secured between the elastic component and an open end of the enclosure; the elastic component includes multiple elastic flaps; the multiple elastic flaps are evenly distributed around an axial direction of the dielectric resonator; one end of each of the elastic flaps is fixedly connected to the main cover, and free ends of the elastic flaps elastically act on a central part of an outer surface of the main cover, to provide an elastic force towards the dielectric resonator. The evenly distributed multiple elastic flaps produce a pressure towards the dielectric resonator. A uniform and stable pressure is produced around the dielectric resonator, to ensure a uniform current density inside the resonant cavity.

Abstract: In wireless communications, many radio frequency bands are used. For each frequency band, there are two frequencies, one for transmitting and the other for receiving. As the band widths are small and separation between adjacent bands is also small, many band pass filters with different band pass frequencies are required for each communication unit such as mobile handset. The invention provides tunable film bulk acoustic resonators TFBARs containing semiconducting piezoelectric layers and methods for tuning and adjusting the resonant properties. When a DC biasing voltage is varied, both the depletion region thickness and neutral region thickness associated in the semiconducting piezoelectric layers varies leading to changes in equivalent capacitances, inductance and resistances and hence the resonance properties and frequencies. A plurality of the present TFBARs are connected into a tunable oscillator or a tunable and selectable microwave filter for selecting and adjusting of the bandpass frequency by varying the biasing voltages.

Abstract: A Yttrium Iron Garnet (YIG) tuned band reject filter using one or more Shunt YIG resonators provides for much wider minimum rejection bandwidths without increasing maximum 3 db bandwidths or spurious response. Various configurations of a tunable shunt YIG tuned band reject filter achieves a wide rejection bandwidth at the low end of the tuning range while keeping the maximum 3 db bandwidth, normally occurring at the high end of the tuning range, to a minimum.

Abstract: A flat cable high-frequency filter includes a dielectric substrate extending in a transmission direction of a high-frequency signal. The dielectric substrate includes dielectric layers stacked on each other. Elongated conductor patterns are provided on a flat surface of one dielectric layer which faces another dielectric layer. The conductor patterns are as wide as possible in the dielectric substrate in accordance with a desired inductance. A capacitive coupling conductor pattern opposes one conductor pattern by a predetermined area with a dielectric layer therebetween. By using a connecting conductor, the capacitive coupling conductor pattern is connected to the conductor pattern which does not oppose the capacitive coupling conductor pattern.

Abstract: A highly compact band pass filter that has excellent mechanical strength is disclosed. A band pass filter according to the present invention employs a dielectric block of substantially rectangular prismatic shape constituted of a first portion lying between a first cross-section of the dielectric block and a second cross-section of the dielectric block substantially parallel to the first cross-section and second and third portions divided by the first portion and metal plates formed on the surfaces of the dielectric block. The first portion of the dielectric block and the metal plates formed thereon are enabled to act as an evanescent waveguide. The second portion of the dielectric block and the metal plates formed thereon are enabled to act as a first resonator. The third portion of the dielectric block and the metal plates formed thereon are enabled to act as a second resonator. The metal plates include a capacitive stub formed on a first surface of the dielectric block which is substantially perpendicular to the cross-sections.
