摘要： An ortho-mode transducer may include a cylindrical common waveguide terminating in a common port, a rectangular vertical branch waveguide in-line with the cylindrical common waveguide and terminating in a vertical port, and a rectangular horizontal branch waveguide normal to the common waveguide and terminating in a horizontal port. The vertical branch waveguide may be configured to couple a first linearly polarized mode from the vertical port to the common waveguide. The horizontal branch waveguide may be configured to couple a second linearly polarized mode, orthogonal to the first linearly polarized mode, from the horizontal port to the common waveguide. A portion of the vertical branch waveguide may overlap a portion of the cylindrical common waveguide. A septum may span the vertical branch waveguide proximate to the overlapping portions of the vertical branch waveguide and the common waveguide. A rectangular symmetry cavity may be opposed to the horizontal branch waveguide.

摘要： A mechanism to connect first and second circular waveguides. A first member includes two or more pins extending radially from a body, the first waveguide coaxial with the body and terminating at a first port at an end face of the body. A second member has a cavity coaxial with the second waveguide and configured to fit over the first member, the second waveguide terminating at a second port within the cavity. Slots disposed around a perimeter of the cavity engage the two or more pins. A cap fits over the second member, the cap including L-shaped slots to engage the two or more pins extending through the slots of the second connecting member. A wave spring between an inside surface of the cap and a shoulder of the second member urges the second port towards the first port when the cap is engaged with the two or more pins.
