A waveguide transition for transitioning from an overmoded waveguide to another waveguide is provided, where one end of the waveguide is configured to connect to a rectangular waveguide and the other end is configured to connect to an elliptical waveguide. The transition has an internal shape having top and bottom walls and two side walls. The top and bottom walls are shaped to join smoothly with waveguides at each end of the transition, while the side walls diminish in height along the length of the transition. The waveguide transition may employ mode filtering to suppress unwanted higher modes. A method of forming waveguide components is also disclosed, involving thixoforming of components in single pieces, the components having internal shapes configured for mold core removal.
