      Can anyone guide me how to plot Odd and Even mode impedances of a 4-port microstrip directional coupler. Driven Terminal Modal

      Hello, 


      Quick question - which tool are you using for your analysis?


      Thank you.

       Hi JarHead,

      I am not tried this method to compare but you can try this suggestion and verify it against known value, to see if it works:


      Set solution type: Driven terminal
      Draw two terminal lines while creating waveport.
      Set differential ports (Right click on the excitation and set proper pair). Your 50Ohm ports will be then 100Ohm for diff, and 25 Ohm for common.
      Run sim, and then 
      Zeven= 2*Zcommon
      Zodd=Zdiff/2

      Thank you,
