摘要： A low-pass filter includes metal stub conductors mounted on a signal conductor at midpoints of adjacent high impedance sections of the signal conductor. The metal stub conductors prevent the occurrence of resonance between the high impedance sections, thereby providing a large attenuation value over a wide frequency band above the cutoff frequency of the low-pass filter.
