One end of the first central electrode defines an input port and the other end thereof defines an output port. One end of the second central electrode defines the input port and the other end thereof defines a ground port. A resistance element and a capacitance element which are connected in parallel with each other are connected in series between the input port and the output port. A switching capacitance unit configured to switch a capacitance is connected in parallel with the resistance element between the input port and the output port.

摘要： An irreversible circuit element includes first and second high pass isolators each including first and second center electrodes intersecting with and being insulated from each other on a ferrite to which a direct-current magnetic field is applied with a permanent magnet. One end of the first center electrode is an output port and the other end thereof is an input port, and one end of the second center electrode is another output port and the other end thereof is a ground port. A pass frequency band of the first isolator is higher than a pass frequency band of the second isolator. Respective output portions of the first and second isolators are electrically connected and defined as one output terminal, and a low pass filter LPF is inserted between the output terminal and the output port of the second isolator.

摘要： In a non-reciprocal circuit element, electric power handling capability is improved, and leakage power between adjacent channels is reduced. In addition, balance is taken between reduction of noise between adjacent ports and an increase in insertion loss. A non-reciprocal circuit element includes a YIG ferrite (10) and a plurality of conductors (15) disposed on the YIG ferrite (10) and intersecting each other in an insulated state. A part of Y of the YIG ferrite (10) is substituted with at least any one element of Ho, Dy, and Gd, or a part of Fe of the YIG ferrite (10) is substituted with Co.

摘要： A non-reciprocal circuit element includes high-pass-type first and second isolators, which are each provided with first and second central electrodes that are arranged on a ferrite so as to cross each other while being insulated from each other, the ferrite being applied with a direct-current magnetic field by permanent magnets. One end of the first central electrode defines an input port and another end of the first central electrode defines an output port, and one end of the second central electrode defines the input port and another end of the second central electrode defines a ground port. A pass frequency band of the first isolator is higher than a pass frequency band of the second isolator. Inputs of the isolators are electrically connected to each other to define a single input terminal IN and a low-pass filter LPF is provided between the input terminal IN and the input port of the second isolator.

摘要： An isolator/circulator can keep a size of a 3-way asymmetric propeller resonator and intensity of magnetism, control the preferred frequency, and improve the insertion loss and isolation characteristic due to reducing the ferrite usage region on the maximum, extend the wide band without the external wide band extension, finally to miniaturize, reduce the fabricating cost by means of a simple fabrication. A microstrip/stripline isolator/circulator having a propeller resonator can be used for the device protection and impedance matching of a system and terminal in a transfer communication, personal communication, CT and satellite communication.
