Wideband VIP power divider with differential output

A novel wideband VIP power divider with out of phase outputs was designed and experimentally verified. The phase difference 180/spl deg/ /spl plusmn/5/spl deg/ and the amplitude difference /spl plusmn/ 0.8 dB of output signals were achieved in 4-26 GHz frequency band. Common ground of all coaxial ports is advantageous for application of the component in some differential measurements.
