Abstract
A balanced-unbalanced conversion element for realizing easy adjustment of a phase balance of two balanced signals is provided. The balanced-unbalanced conversion element includes a first ¼-wavelength resonant line coupled to a first balanced terminal, a second ¼-wavelength resonant line coupled to a second balanced terminal, and a ½-wavelength resonant line. The ½-wavelength resonant line includes a first open-end-side line coupled to an unbalanced terminal and the first ¼-wavelength resonator and a second open-end-side line coupled to the second ¼-wavelength resonator. In addition, a width of the first open-end-side line differs from a width of the second open-end-side line.
