Waveguide flanges for joining waveguide sections or components are designed to achieve mechanical strength and exhibit desired electrical properties such as relatively low insertion loss and high return loss. The present invention contemplates waveguide interfaces with a new choke flange designed to engage with a shield flange and provide a joint with improved electrical properties. The new choke designs produce a virtual continuity through the waveguide joints and minimize electrical energy leakage. The electrical and mechanical properties of the joint in the waveguide interfaces are robust and able to tolerate lower levels of parts precision, imperfect mating of the flanges without metal-to-metal contact and gaps up to 0. 06″ or more between the mating flange surfaces.

Systems and methods for a filtering wave energy using a rectangular-to-circular waveguide transition are discussed herein. An exemplary system comprises a rectangular-to-circular waveguide transition and a filter card. The rectangular-to-circular waveguide transition may include a front section and a back section opposite the front section, the rectangular-to-circular waveguide transition defining a circular hole extending from the front section of the rectangular-to-circular waveguide transition through the back section, the rectangular-to-circular waveguide transition further having a first arcuate region on the face of the transition, the first arcuate region defining a first cavity extending from the circular hole through the first arcuate region, the rectangular-to-circular waveguide transition also having a second arcuate region defining a second cavity opposite the first cavity, the second cavity extending from the circular hole through the second arcuate region. The filter card may be configured to be placed across the circular hole of the rectangular-to-circular waveguide transition.
