    摘要: A bandpass filter is capable of forming attenuation extremes on both sides of a passband. Multiple microstrip line resonators, one end of each being an open terminal and the other end connecting to a ground electrode, are provided in a row, and the inner microstrip line resonators are bent in a C-shape so that the open terminals of the outer microstrip line resonators project further than the inner microstrip line resonators. The line of sight between the open terminals of the microstrip line resonators is improved and capacitance is formed there, so that attenuation extremes can be formed on both sides of the passband, and the amount of attenuation can be increased.

    摘要: The invention provides a high frequency filter which can facilitate filter-characteristic adjustments and miniaturization and can obtain an excellent broadband characteristic. In addition, the invention provides a filter device using the high frequency filter, and an electronic apparatus incorporating the same. In this filter, a ground electrode is arranged on one of the main surfaces of a dielectric substrate. On the other main surface thereof there are arranged two or more microstrip lines, and one end of each microstrip line is grounded via a through-hole to form a high frequency filter. The microstrip lines and the shared through-hole constitute microstrip line resonators, which are coupled via the inductance of the through-hole. With this arrangement, there is no need for an additional coupling element. Thus, the size of the high frequency filter can be reduced. Furthermore, since a large coupling coefficient can be obtained, the high frequency filter can have a broadband characteristic.

    摘要: An unbalanced-to-balanced converter (balun) comprising three distributed-constant lines. In one distributed-constant line, a standing wave is generated. Disposed adjacent thereto is another distributed-constant line to which the power of the standing wave is transferred. A signal input to the unbalanced-to-balanced converter is divided into two signals having phases 180 degrees apart and the same level.

    摘要: A line width on the grounded side of distributed-constant-line-type resonators which form a distributed-constant-line-type filter is made wider than a line width on the open side. By increasing the line width on the grounded side, where a larger electric current flows, of a distributed-constant-line-type resonator, the line resistance of the distributed-constant line decreases, making it possible to reduce the loss of the distributed-constant-line-type resonator and further to reduce the insertion loss of the distributed-constant-line-type filter. Further, by decreasing the line width on the open side to less than the line width on the grounded side, an increase in the size of the filter because the line width on the grounded side is increased can be prevented.
