摘要: Two novel high-selectivity wideband balanced filters using symmetrical/asymmetrical coupled lines with open/shorted stubs are proposed in this letter. Multiple transmission zeros achieved to obtain sharp rejection and good out-of-band suppression for the differential mode, which fixed can be realized by half-wavelength open adjustable loaded lines. In addition, all allocated suppress common mode from 0 GHz $3f_{0}$ ( $f_{0}$ is center frequency of passband). 3-dB fractional bandwidths 22% 21% are, respectively, designed fabricated.
