Abstract

See full text

A low pass filter 6 comprises an inductor unit 8 comprising first and second inductors 11 and 12, an input side capacitor unit 7 provided on a signal input side of the inductor unit 8, and an output side capacitor unit 9 provided on a signal output side of the inductor unit 8. The input side capacitor unit 7 comprises a first capacitor 21 provided between the signal lines. Further, the input side capacitor unit 7 comprises a second capacitor 22 wherein one end is connected to a signal input end 11a of the first inductor 11, and the other end is connected to a ground (GND), and a third capacitor 23 wherein one end is connected to a signal input end 12a of the second inductor 12, and the other end is connected to a ground (GND).
