Title:
LC FILTER
Document Type and Number:
WIPO Patent Application WO/2018/092442
Kind Code:
A1
Abstract:
In order to reduce LC filter insertion loss, an LC filter (1) according to an embodiment of the present invention is provided with a first LC resonator (LC2) and a second LC resonator (LC3). The first LC resonator (LC2) and the second LC resonator (LC3) include a first inductor (L2) and a second inductor (L3), respectively. When viewed in a plan view from the winding axis direction of the first inductor (L2), an air-core portion formed by the first inductor (L2) does not match an air-core portion formed by the second inductor (L3). The LC filter (1) is further provided with a bypass conductor (BP1). The bypass conductor (BP1) connects an intermediate portion of the first inductor (L2) between one end and the other end of the first inductor (L2), and an intermediate portion of the second inductor (L3) between one end and the other end of the second inductor (L3).
