A power combiner for combining a plurality of radio frequency signals into a combined output signal includes: a circular waveguide having a cross-section and three or more waveguides, each waveguide morphing to align with a common axis at a cross-section of the circular waveguide wherein each one of the three or more rectangular input waveguides gradually transitions from a rectangular cross-section to a cross-section resembling a pie slice of a composite circular cross section.

Embodiments of the present disclosure use customizable waveguides that can be positioned next to each other in a structure that contains one single flange to provide a physical connection for the waveguides. In this fashion, many waveguides can be positioned within a small area to accommodate a tightly packed patch antenna array so that the waveguides can be positioned very close to the socket. As such, embodiments of the present disclosure allow more waveguides to be packed into a small area by providing a single structure that houses many waveguides and share only a single flange connection element that can be sized appropriately.

Embodiments of the present disclosure utilize customizable waveguide fabrication technologies (e.g., 3D printer technology) and patch antenna arrays to create adaptable wave interfaces that can provide efficient signal routing for an ATE system. In this fashion, embodiments of the present disclosure allow for arbitrary waveguide routing from port to port and create high density port spacing at the PCB level and which specifically eliminates the large flange required of prior art waveguides. Furthermore, embodiments include the ability to integrate different waveguide components, including power splitters, couplers, terminations, etc., into a single structure. Thus, embodiments of the present disclosure can reduce signal path losses and simplify the mechanical construction of ATE systems while eliminating the need for coax cables and minimizing the length of PCB microstrips.

A switching device includes a first electrode at least partially disposed within a sealed chamber. The sealed chamber encloses a plasma phase change material. The switching device includes a second electrode at least partially disposed within the sealed chamber. The second electrode is physically separated from the first electrode. When subjected to a signal that satisfies a threshold, the plasma phase change material forms a plasma within the sealed chamber. The first electrode is electrically coupled to the second electrode via the plasma when the plasma is formed. The first electrode is electrically isolated from the second electrode when the plasma is not formed. The switching device includes a first connector electrically coupled to the first electrode and a second connector electrically coupled to the second electrode. The first connector, the second connector, or both, are configured to receive the signal.

The present application discloses embodiments that relate to an electromagnetic apparatus. In one aspect, the present apparatus includes a circuit board configured to propagate an electromagnetic signal. The apparatus also includes a waveguide configured to propagate an electromagnetic signal. The apparatus further includes a coupling port configured to couple a signal between the circuit board and the waveguide, where the coupling port has dimensions based on a desired impedance of the port.

A board to board contactless interconnect system includes a first circuit board for launching at st one microwave signal into a cavity of a first waveguide secured thereto. A second waveguide, secured to a second circuit board, is coupleable to the first waveguide to receive the at least one microwave signal in a cavity of the second waveguide and conduct the at least one microwave signal onto a microwave receiver aligned with the cavity on the second circuit board. The waveguides may be separable and may include additional waveguides. Conductive gaskets with apertures for microwave signals to pass through are positioned between the waveguides and between each circuit board and a waveguide to prevent leakage of microwave energy therebetween. Some embodiments may pass signals through a sealed boundary and maintain integrity of the seal. Such embodiments may have a third waveguide interposed between the first and second waveguides.

High speed waveguide-based data communication systems are disclosed. Such systems may include separable electrical connectors, forming signal propagation paths between electronic assemblies with one or more waveguides.

The invention relates to a microwave circular polarizer including: a first outer conductor; a second outer conductor connected to the first outer conductor forming a first step discontinuity therewith; and a third outer conductor connected to the second outer conductor forming a second step discontinuity therewith. An inner conductor is provided which extends inside and is spaced apart from the first, second and third outer conductors. The first and second outer conductors are axially asymmetric with respect to the inner conductor, and the third outer conductor is axially symmetric with respect to the inner conductor. The microwave circular polarizer includes first and second rectangular waveguide ports in signal communication with an internal cavity through, respectively, a first rectangular aperture and a second rectangular aperture formed through the first outer conductor. The microwave circular polarizer further includes a first septum and a second septum.

The described features include a scalable waveguide architecture for a waveguide device. The waveguide device may be split into one or more waveguide blocks instead of manufacturing increasingly larger single-piece waveguide devices. Described techniques provide for a radio-frequency (RF) seal between such waveguide blocks that may facilitate greater manufacturing tolerances while maintaining an effective RF seal at the junction of the waveguide blocks. The described techniques include channels within one or more waveguide blocks opening to the dielectric gap between the waveguide blocks. The channels may, for each of multiple waveguides joined at the interface between waveguide blocks, be included in one or both waveguide blocks and may be in a single waveguide dimension relative to the multiple waveguides, or extend for more than one waveguide dimensions.

A microwave or radio frequency (RF) device includes a substrate and a cover. The substrate has a first surface and an opposing second surface, the first surface including a first RF component and a second RF component electrically coupled to the first RF component in series. The cover is disposed over the first surface of the substrate, where the cover includes a first portion with a first width covering the first RF component, where the first portion and the first surface define a first waveguide cavity having the first width, and a second portion with a second width, less than the first width, covering the second RF component, where the second portion and the first surface define a second waveguide cavity having the second width.
