摘要： A dielectric filter or a dielectric duplexer is provided which comprises a dielectric block in a substantially rectangular parallelepiped shape, having a pair of opposite parallel end-faces and plural sides extending between the paired opposite end-faces, one of the plural sides being a mounting face; plural resonator holes elongating through the inside of the dielectric block across the paired opposite end-faces; inner conductors provided on the inner walls of the plural resonator holes, respectively; an outer conductor provided on the outside of the dielectric block; input-output electrodes provided only on one of the paired opposite end-faces, separated from the outer conductor, and capacitance-coupled to the predetermined inner conductors, respectively; and conductive terminals for external connection, connected to the input-output electrodes, having at least portions thereof lying substantially in the same plane as the mounting face. In the dielectric filter or the dielectric duplexer, since input-output electrode are provided on the end-face of the dielectric block, not provided on the sides of the dielectric block, the deterioration of Q0, caused by the input-output electrodes, can be reduced. Accordingly, the insertion loss and the attenuation characteristics are improved.

摘要： There is disclosed a dielectric filter comprising: an attenuation band in proximity to a pass band; a threshold-frequency position of a determined maximum insertion loss being arranged close to a shoulder portion of a waveform exhibiting pass characteristics in which insertion losses increase in a region from the pass band to the attenuation band; temperature characteristics of a dielectric material being determined in such a manner that the shoulder portion moves toward the attenuation-band direction according to an increase and decrease in temperature. In the above dielectric filter, the deterioration of insertion-loss characteristics with respect to temperature changes is improved so that good characteristics are exhibited over a wide range of temperatures.

摘要： A balanced-unbalanced transformation device includes a plate-like dielectric substrate having a ground electrode and a plurality of major surface electrodes formed thereon. Two of the major surface electrodes are connected to the ground electrode via short-circuit side surface electrodes so as to form ¼ wavelength resonator transmission lines. A third major surface electrode is disposed between the two major surface electrodes and has either end open so as to form a ½ wavelength resonator transmission line. A balancing characteristic adjustment side surface electrode is provided on a side surface of the dielectric substrate. By adjusting a capacitance formed between the balancing characteristic adjustment side surface electrode and the third major surface electrode, a phase balance between two balanced signals is set to a desired value.

摘要： A dielectric filter includes a dielectric block having inner-conductor-formed holes extending from a first face of the dielectric block to a second face opposed to the first face. Inner conductors are formed inside the inner-conductor-formed holes such that both ends of the inner-conductor-formed holes are open-circuited. On the exterior surface of the dielectric block, balanced input/output terminals are capacitively coupled to the open ends of the inner-conductor-formed holes. A metal cover is provided so as to cover one of the first or second face of the dielectric block. The metal cover functions as a short-circuit conductor in a spurious mode such as a TE mode other than a TEM mode, and hence the influence of the spurious mode is avoided.
