Abstract

To develop common mode filter design, a tri-section quarter wavelength resonator common mode filter is introduced in this paper. The step impedance quarter wavelength resonator in common mode provides capabilities of tunable suppression bands by controlling the 1^st and 3^rd resonant frequency. In addition, the transmission zero in differential mode due to the difference of phase velocity between common mode and differential mode is moved to higher frequency band as a result of applying tri-section design.
