Title:
NON-RECIPROCAL CIRCUIT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/079792
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress, with a simple structure, fluctuations in characteristics due to temperature, without changing the materials of magnetic bodies and magnets in a non-reciprocal circuit element. This non-reciprocal circuit element comprises: a magnetic body (32) to which a direct-current magnetic field (G) is applied; a plurality of center electrodes (35, 36) arranged with respect to the magnetic body (32) in an intersecting manner in a state insulated from one another; a terminating resistor (R) connected between input and output ports (P1, P2) in parallel to one of the center electrodes (35, 36); a variable capacitance element (C11) having a variable capacitance and connected between the input and output ports (P1, P2) in parallel to the terminating resistor (R); and a thermistor element (S) connected in series with the variable capacitance element (C11) to a control power supply circuit (E) of the variable capacitance element (C11).
