Abstract
A high-frequency filter includes at least one magnetoresistive effect element; a first port through which a high-frequency signal is input; a second port through which a high-frequency signal is output; and a signal line.
Claims10
A high-frequency filter comprising:
- at least one magnetoresistive effect element that is electrically connected between a first electrode and a second electrode;
- a first port through which a high-frequency signal is input;
- a second port through which a high-frequency signal is output;
- a signal line having a first portion and a second portion;
- and
- a direct-current input terminal connected to the signal line so as to apply a direct current to the at least one magnetoresistive effect element,
- wherein the first portion of the signal line is connected between the first port and the first electrode and the second portion of the signal line is connected between the second electrode and the second port, thereby the first port, the at least one magnetoresistive effect element, and the second port are connected electrically in series in this order via the signal line.
