发明名称 NON-RECIPROCAL CIRCUIT ELEMENT
摘要 <p>In a non-reciprocal circuit element, good isolation characteristics are obtained across a wide bandwidth, and the isolation frequency can be adjusted. A non-reciprocal circuit element provided with a ferrite (32) in which a direct-current magnetic field is applied using a permanent magnet, and a first center electrode (35) and second center electrode (36) disposed intersecting in a mutually insulated state at the ferrite (32). The first center electrode (35) has one end connected to an input port (P1), and the other end connected to an output port (P2). The second center electrode (36) has one end connected to the output port (P2) and the other end connected to a ground. A first capacitor (C1) is connected between the input port (P1) and the output port (P2), and a second capacitor (C2) is connected between the output port (P2) and the ground. A resistor (R) is connected between the input port (P1) and the output port (P2), and a third capacitor (C3) and an inductor (L3) are connected serially to the resistor (R). A fourth capacitor (CA) is connected between the input port (P1) and the ground. The first capacitor (C1) and the third capacitor (C3) have variable capacitance.</p>
