Abstract
A high-frequency filter includes a first terminal, a second terminal, a third terminal, a first inductor, a second inductor, a third inductor, and a fourth inductor. The first inductor and the second inductor are connected in series to each other between the first terminal and the second terminal. The third inductor and the fourth inductor are connected in parallel to each other between the third terminal and a node of the first inductor and the second inductor. The connection between the first inductor and the second inductor is an additive polarity connection. The connection between the third inductor and the fourth inductor is an additive polarity connection.
