摘要： PURPOSE: To simplify the assembling and adjustment of a ladder type ceramic filter and to reduce insertion loss by selecting a band width for an input stage unit to be the same that for an output stage unit and selecting the band width to be larger than a band width of an intermediate stage unit. CONSTITUTION: In the ladder type piezoelectric filter of, e.g. 4-unit configuration, an L-shaped connection is adopted for a series element 1 and a parallel element 2 in each unit, and each L-shaped connection element is being connected from the input toward the output in the order of an input stage unit 3, intermediate stage units 5, and an output stage unit 4. The band width of the input stage unit 3 and that of the output stage unit 4 are designed maximum, the designed band width of each unit from the input stage unit 3 to the intermediate stage unit 5 is gradually decreased, and the designed band width of each unit from the intermediate stage unit 5 to the output stage unit 4 is gradually increased. Thus, the group delay characteristic is controlled almost without changing the design band width.

摘要： PURPOSE:To shift a resonance frequency of spurious radiation toward high frequencies on purpose without change of a resonance frequency of the lengthwise vibration of a paper-tablet piezoelectric resonator and to process the resonator simply by cutting off one corner among corners formed by the electrode faces of the paper-tablet piezoelectric resonance plate and side faces employing the lengthwise vibration. CONSTITUTION:Electrodes 4, 5 are provided to one face 2 on the piezoelectric resonator plate 1 and other face 3 opposite to the face 2 in parallel and one corner 6 among corners formed by electrode faces and side faces of the piezoelectric resonator plate 1 is cut out. The effective values of the width and thickness of the resonator are simultaneously changed by cutting off the one corner in this way and the frequency of the spurious radiation is shifted toward higher frequencies without revision of the resonance frequency in the lengthwise direction. In this case, the resonance frequency of spurious radiation is shifted toward higher frequencies as the corner is much more cut off. Or the similar effect is obtained by cutting off the one corner 6 much more further to form a trapezoidal cross section perpendicular to the lengthwise direction of the piezoelectric resonance plate 1.
