According to the present invention, a waveguide assembly is provided and includes a common input waveguide aligned along a first axis. The input waveguide supports two frequency bands and one or more polarities, namely high and low band signals of two polarities which are typically supplied using a feed horn which is coaxially aligned with the input waveguide. The waveguide assembly also includes an output waveguide for supporting and discharging the low band signal (one or more polarities). The output waveguide extends along a second axis which is parallel to the first axis containing the input waveguide but is displaced therefrom. In order to accomplish this the waveguide assembly has two or more waveguides connecting the input waveguide to the output waveguide. The waveguides are disposed substantially perpendicular to the input and output waveguides such that the low band signal is fed into the input waveguide and then separated therefrom by being carried within one or more planes defined by the waveguides before being discharged through the output waveguide.

Multi-port multi-band transceiver interface assembly

A slip joint polarizer including a stationary waveguide rotatably connected to a moveable waveguide, e.g. an ortho mode transducer, by a mating interface, such as a pair of rotatable mating flanges. The moveable waveguide is rotatable with respect to the stationary waveguide to adjust at least one of receive and transmit polarity. A probe extends axially in the moveable waveguide, passing through the mating interface and into the stationary waveguide. The probe may be attached to the moveable waveguide so that the two rotate simultaneously. Alternatively, the probe may rotate independent of the moveable waveguide to adjust for transmit polarity. During installation, the moveable waveguide is rotated with respect to the stationary waveguide in order to adjust receive and/or transmit polarity. Once properly adjusted, the rotatable mating flanges are locked together to prevent movement.
