A waveguide assembly is disclosed herein. In an embodiment, a waveguide assembly includes a circuit board, a housing and a waveguide filter channel. The circuit board has at least one waveguide interface formed from an electrically conductive material. The housing is configured to be attached to the circuit board so as to align with the at least one waveguide interface. The waveguide filter channel is formed between the circuit board and the housing, with the circuit board and the housing each forming at least a portion of the waveguide filter channel. The waveguide filter channel is configured to at least one of (i) receive a radio frequency signal from the at least one waveguide interface or (ii) output the radio frequency signal to the at least one waveguide interface.

Waveguide assembly

A multiport waveguide device is disclosed herein. In an embodiment, a multiport waveguide device includes a first receiving port structure configured to guide a first incoming RF signal, a second receiving port structure configured to guide a second incoming RF signal, a first transmitting port structure configured to guide a first outgoing RF signal, and a second transmitting port structure configured to guide a second outgoing RF signal. The multiport waveguide device also includes common port structure configured to simultaneously guide the first incoming RF signal, the second incoming RF signal, the first outgoing RF signal, and the second outgoing RF signal through a common port.

Multiport waveguide device

A microstrip-to-waveguide transition includes a substrate and a waveguide. The substrate has a metal layer, a ground layer and a dielectric layer disposed between the metal layer and a ground layer. The substrate includes a microstrip line impedance transformer and a substrate integrated waveguide that is electromagnetically coupled to the microstrip line impedance transformer. The substrate integrated waveguide has a 90 degree substrate integrated waveguide bend section at an end portion thereof. The waveguide is arranged perpendicularly relative to the substrate. The waveguide is electromagnetically coupled to the substrate integrated waveguide at the 90 degree substrate integrated waveguide bend section. The microstrip-to-waveguide transition is free of a back-short at a location corresponding to the 90 degree substrate integrated waveguide bend section.
