An L-type coaxial connector is connected to a coaxial cable including a central conductor and an external conductor, and includes a housing, a bushing, and a socket. The housing includes a housing main body, a back-side section, and a crimp section. The housing main body has a first cut section. The back-side section includes a lid section and an extending section extending from the lid section and above which the external conductor is placed. The crimp section extends from the extending section, and its leading end section is bent so as to be opposed to the extending section such that the coaxial cable is interposed therebetween. The extending section has a second cut section, and a joining member joining the external conductor and the extending section is present inside the second cut section.

L-type coaxial connector and method for manufacturing L-type coaxial connector

A dielectric resonator device including a circuit substrate with a top surface provided with transmission lines, and a bottom surface provided with a ground electrode; a dielectric substrate with opposite surfaces that are respectively provided with electrodes having circular openings so as to form a TE010-mode resonator; and an insulating layer disposed between the ground electrode of the circuit substrate and the electrodes of the TE010-mode resonator. The TE010-mode resonator is attached to the circuit substrate with an insulative adhesive. Accordingly, a current path remains unchanged even if the circuit substrate and the TE010-mode resonator are partially disengaged from each other, thereby achieving stable characteristics.

Dielectric resonator device, oscillator and transmitter-receiver apparatus

A filter includes a dielectric resonator, a cavity for holding the dielectric resonator therein, an external connector mounted on the cavity, and a coupling loop connected to the external connector so as to electromagnetically couple with the dielectric resonator. The coupling loop is formed by bending a metal plate nearly into the shape of an L, and is provided with a rib extending in a direction that is not parallel to the bending line.

Filter, duplexer, and communication device

A long-life highly reliable dielectric resonator, a dielectric filter using the dielectric resonator and a dielectric duplexer, in which the heat accumulated in concave portions is dissipated. The dielectric resonator comprises a frame, a column-shaped dielectric resonant element disposed so as to be integral with the frame at ends thereof, the concave portions formed from the external surface of the frame into the dielectric resonant element in the direction of the axis of the dielectric resonant element, a conductor formed on the overall outer surface of the frame including inside the concave portions, and thermal-conducting means inserted in the concave portions.
