专利汇可以提供Structure for idt exciting type piezoelectric resonator专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain an IDT exciting type piezoelectric resonator with less loss without decreasing yield by making the pitch of an IDT and a reflector equal to each other, forming the gap of both to be in complete continuous equal period, inserting a capacitor in series with the IDT so as to vary the capacitor. CONSTITUTION:A period LT of IDT electrodes 2 of an IDT exciting type piezoelectric resonator and a period LR of a reflector are formed to be continuously equal, the line width is made equal and a static capacitance of an interdigital conductor pattern 4 is inserted in series with said IDT 2. Since the resonance frequency of the resonator varies with the series capacitance C, the C is adjusted close to a prescribed value thereby adjusting the resonance frequency to be coincident with the desired value. Thus, the manufacturing dispersion in the resonance frequency is corrected and the yield is improved considerably.,下面是Structure for idt exciting type piezoelectric resonator专利的具体信息内容。
