Abstract
The mode convertor employs two intermediate modes, a coaxial TEM and a rectangular waveguide TE.sub.10 mode, in the transition between the TM.sub.01 and TE.sub.11 circular waveguide modes. The coaxial line provides isolation while acting as a mode filter between the device input and output ports. The rectangular waveguide provides a wide mode separation ratio between the TE.sub.10 and TM.sub.11 modes. The TE.sub.10 mode then transitions into the TE.sub.11 in the circular output waveguide. The coaxial section keeps the output TE.sub.11 mode from scattering back to the input, and the rectangular section keeps the TM.sub.01 from being excited in the output.
