Title:
マイクロ波フィルタ
Document Type and Number:
Japanese Patent JP6581429
Kind Code:
B2
Abstract:
A microwave filter includes a strip transmission line and a filtering assembly connected to the strip transmission line. The transmission line has an input terminal and an output terminal. The filtering assembly includes a strip first primary branch connected directly to a first connection point of the transmission line. The first primary branch includes a first body portion and a first bent portion at a first end of the first body portion, where the first bent portion is connected directly to the first connection point, and the first body portion is substantially parallel to a body portion of the transmission line. With the microwave filter incorporated in an electric motor, the impedance curve of the transmission line can be matched with a high-frequency EMI curve, and therefore the filtering effect is enhanced, EMI is suppressed and the EMC level improved.
