Transmission line type resonator, and high frequency filter, high frequency module and wireless device using the same

摘要

PROBLEM TO BE SOLVED: To provide a transmission-line resonator improving the problem that a high-frequency current flowing through the transmission-line resonator is changed into a heat energy by the electric resistance of the transmission-line resonator and having a low loss.;SOLUTION: The transmission-line resonator 7 is composed of a laminate 8 laminating a plurality of dielectric sheets 11. The transmission-line resonator 7 has composite right-group left-group transmission lines arranged among a plurality of these dielectric sheets 11, and external connecting terminals 9 arranged on the end faces of the transmission-line resonator 7 and connected to the composite right-group left-group transmission lines. According to the constitution, since the transmission-line resonator 7 uses the composite right-group left-group transmission lines, the transmission-line resonator 7 has the low loss.;COPYRIGHT: (C)2008,JPO&INPIT
