A wideband‐balanced bandpass filter is presented using two half‐wavelength transmission lines, two coupled lines and one‐stepped impedance stub. Compared to the reported wideband‐balanced bandpass filters, the proposed one shows the advantages of small total length, high‐frequency selectivity and wideband common‐mode (CM) suppression. The bandwidth of CM suppression and differential‐mode transmission, and the positions of transmission zeros are controllable by the parameters. One prototype was designed, fabricated and measured with the total length of 2 λ g ( λ g is the guided wavelength at the centre frequency f 0 ), 3 dB fractional bandwidth of 61% and 15 dB CM suppression bandwidth of 3.67 f 0 .
