摘要： PURPOSE: To provide an instrument with high measuring accuracy for measuring a temperature coefficient of a dielectric resonator which can hold the dielectric resonator stably without using an adhesive. CONSTITUTION: A ceramic cavity 2 having a supporting stage 3 inside is accommodated in a metallic case 1. A holding guide 6 is fitted at a metallic upper lid 5 covering the upper opening face of the cavity 2. A holding screw 10 is meshed at an inner peripheral face of the guide 6. A holding rod 7 is also set to the upper lid 5. An upper part, of the holding rod 7 is inserted through the screw 10 and a lower part of the rod is meshed at the inner peripheral face of the guide 6. A coil spring 8 is wound around the holding rod 7. A supporting rod 9 made of a dielectric material is inserted through the upper lid 5 and fixed at the front end of the rod 7. In this structure, a dielectric resonator 20 is held by the supporting stage 3 and the supporting rod 9 owing to the spring pressure of the spring 8. The cavity 2, supporting stage 3 and supporting rod 9 are formed of a material having approximately the same thermal expansion coefficient as the dielectric resonator 20.

摘要： A dielectric resonator comprising a resonator section (11) and a supporting base section (12) which are made of the same dielectric material as a single unit. The resonator section (11) and the supporting base section (12) have substantially the same outside diameter. A concave section (13) having a trapezoidal cross-sectional shape is provided within the supporting base section (12) such that the inside diameter of the supporting base section (12) becomes smaller in the direction from the end face, which is used as a mounting face, and toward the resonator section (11).

摘要： A compact local oscillator circuit for use in receiving signals from broadcasting satellites and communications satellites comprises two FET stripline oscillators sharing a common dielectric resonator 1 mounted between respective coupling lines 21b,21c. Each oscillator excites a distinct and separate mode in the resonator. One mode may be of TE01 type and the other of TM01 type. Unwanted modes may be eliminated by cutouts, holes or slots in the resonator. The resonator may be circular or square. The output frequencies may be 10.678 GHz and 11.200 GHz.

摘要： The dielectric resonator apparatus is characterized in that electric walls exist on one plane or two including the central axis of the electromagnetic field distribution in the using mode of a dielectric resonator, a dielectric resonator with either of dielectrics between the electric wall being removed in shape is provided by plurality, an equivalent axis is common to the central axis of each of the dielectric resonators, with the dielectric resonators being inductively coupled in the axial direction. A dielectric resonator which prevents the current from being concentrated on the central axis of the electromagnetic field distribution, is collectively smaller in the Joule loss and is higher in Q. The dielectric resonator of the present invention is characterized in that the dielectric close to the central axis is removed, wherein electric walls exist on one plane or two including the central axis of the electromagnetic field distribution in a dielectric resonator using, for instance, a TE01 delta mode, with either of dielectrics between the electric wall being removed in shape.

摘要： A mechanism for adjusting the resonance frequency of a dielectric resonator having TE01 delta mode as its operation mode under the presence of the electromagnetic field including: a hole extending along the axis of the dielectric resonator; a tuning bar, made of a dielectric material of a low loss, having a male screw formed on the peripheral surface thereof; and a female screw, to engage the male screw, formed on the wall of the hole. The tuning bar is reciprocated in the hole with the tuning bar engaging the hole so as to adjust the resonance frequency.

摘要： A dielectric resonance element resonating in the TE01 delta mode and a protrusion portion disposed in a direction perpendicular to the bottom surface of the dielectric resonance element are integrally molded, and the side face at the outer periphery of the protrusion portion is tilted such that the area on the bottom-surface side of the dielectric resonance element is larger than the area of the lower surface of the protrusion portion. Because of such a structure, the magnetic field of the dielectric resonance element spreads to the tilted portion of the side face at the outer periphery of the protrusion portion and around the tilted portion of the side face, and the magnetic field distribution increases under the dielectric resonance element. Even if an input-output electrode is disposed at a location away from the protrusion portion, the input-output electrode is strongly coupled to the dielectric resonance element, resulting in a sufficient coupling.
