Various embodiments of a vacuum electronic device, a hybrid magnet for a vacuum electronic device and methods of making a hybrid magnet for a vacuum electronic device are disclosed herein. In one embodiment, a hybrid magnet for a vacuum electronic device includes a first magnet, a second magnet positioned in spaced-apart relation with the first magnet and defining a gap between the first magnet and the second magnet, and a non-magnetic spacer positioned in a portion of the gap between the first magnet and second magnet and connected to the first magnet and the second magnet.

Hybrid magnet for vacuum electronic device

Various apparatuses and methods for a vacuum electronic device are disclosed herein. In one embodiment, a vacuum electronic device includes a vacuum housing, an array of slow wave structures inside the vacuum housing sharing a common electron beam tunnel, an electron beam input port at a first end of the common electron beam tunnel, and an electron beam output port at a second end of the common electron beam tunnel.

Vacuum electronic device

Various embodiments of a coupled cavity traveling wave tube are disclosed herein. For example, some embodiments provide a coupled cavity traveling wave tube including a plurality of core segments arranged in spaced-apart fashion to form an electron beam tunnel, a first longitudinal member adjacent the plurality of core segments alternately extending toward and receding from successive core segments, and a second longitudinal member adjacent to the plurality of core segments alternately extending toward and receding from successive core segments. The first and second longitudinal members are offset to extend toward different core segments.

Coupled cavity traveling wave tube

Embodiments of the present invention include helical, ring bar and tunnel ladder slow wave structures (SWSs). Embodiments of methods of micro-fabricating such SWSs are also disclosed. Embodiments of high frequency electromagnetic devices including such SWSs are also disclosed. Exemplary high frequency electromagnetic devices may include a traveling wave tube, a traveling wave tube amplifier, a back wave oscillator, as part of a linear accelerator, a microwave power module, a klystron or a millimeter-wave power module.

Method of micro-fabrication of a helical slow wave structure using photo-resist processes

A vertical transformer that comprises a primary and a secondary winding, wherein one winding is positioned on a first plane, and the other winding is positioned on a second plane. The primary and secondary windings are separated by a dielectric substrate. In one embodiment, the primary and secondary windings are configured to use the same ground reference, and terminals in the center of each winding are connected to the ground reference by a via hole to form an in-phase transformer. In a second embodiment, a center terminal of one winding and an outbound terminal of the other winding are connected to the ground reference to form an opposite-phase transformer. In the second embodiment, a dielectric substrate is positioned between one of the windings and a ground plane.
