At a glance: Key parameters
The OMT is a three-port device. It has a square waveguide common mode port supporting two orthogonal modes and a pair of rectangular waveguide ports that each support a single mode. Every OMT is tested on a vector network analyzer to ensure conformity. The test data is
provided to the customer. (1) Flange mates to a standard WR-6.5 flange but has a square waveguide. (2) Insertion loss between a single-mode rectangular port and the corresponding polarization on the common port. (3) Cross-polarization coupling between a rectangular waveguide port and the opposite mode on the common port.
