Waveguide assembly

A waveguide assembly comprising:

• a circuit board having at least one waveguide interface and at least one air cavity, the at least one waveguide interface formed from an electrically conductive material and configured to launch or receive a radio frequency signal, the at least one air cavity aligned with the at least one waveguide interface;
• and
• a housing forming at least a portion of a waveguide filter channel therein, the housing being attached to the circuit board such that the at least one waveguide interface is located between the waveguide filter channel and the at least one air cavity.

A waveguide assembly comprising:

• a circuit board having a first waveguide interface formed from an electrically conductive material and a second waveguide interface formed from an electrically conductive material, the first waveguide interface separated from the second waveguide interface on a surface of the circuit board;
• and
• a housing including a serpentine inner surface, the housing forming at least a portion of a waveguide filter channel therein between the serpentine inner surface and the circuit board, the housing being attached to the circuit board such that the waveguide filter channel is aligned with the first waveguide interface and the second waveguide interface to place the first waveguide interface in signal communication with the second waveguide interface such that a radio frequency signal can be transmitted from the first waveguide interface to the second waveguide interface.
