Abstract

In a waveguide twist which provides orthogonal rotation of both direction and polarization, TE10—mode energy in waveguide W1 is coupled via iris I1 to a transformer cavity capable of exciting both TE10 and TE01 modes. The TE01 mode is coupled via iris I2 to output waveguide W2. Transformers may be interposed between one or both waveguides and their associated irises to increase bandwidth. The configuration facilitates manufacture in two halves by simple machining or casting.
