ABSTRACT:
A layered low-pass filter includes: a first inductor and a second inductor that are connected in series and are located between an input terminal and an output terminal; a first capacitor connected in parallel to the first inductor; a second capacitor connected in parallel to the second inductor; and third to fifth capacitors and third to fifth inductors. The output of the first inductor and the input of the second inductor are connected to the ground via the third capacitor and the third inductor connected in series. The input of the first inductor is connected to the ground via the fourth capacitor and the fourth inductor connected in series. The output of the second inductor is connected to the ground via the fifth capacitor and the fifth inductor8connected in series.
