A device includes a first substrate having a principal surface; a second substrate having a principal surface, in which the first substrate is bump-bonded to the second substrate such that the principal surface of the first substrate faces the principal surface of the second substrate; a circuit element having a microwave frequency resonance mode, in which a first portion of the circuit element is arranged on the principal surface of the first substrate and a second portion of the circuit element is arranged on the principal surface of the second substrate; and a first bump bond connected to the first portion of the circuit element and to the second portion of the circuit element, in which the first superconductor bump bond provides an electrical connection between the first portion and the second portion.

A filter comprising a flexible PCB with one or more signal tracks on one side. A electromagnetically absorbing material covers the signal tracks. An insulating material may be provided between the signal tracks and the electromagnetically absorbing material. The PCB is then folded or rolled to take up less space. The PCB may be first folded and then rolled to have both ends of the signal tracks available at the outer portion of the roll.

This document a two-part folded waveguide with horns. For example, a waveguide includes a channel with an opening in a longitudinal direction at one end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the channel. One part of the waveguide defines a surface of the channel featuring a plurality of radiation slots in the shape of a horn, which allows the two parts of the waveguide to be arranged and configured as one component. A first part of the waveguide has slots and an upper half of the walls of the channel and a second part provides a lower half of the walls of the channel and a surface of the channel opposite the slots. Using horns in combination with two parts enables ease of manufacturing a waveguide with an internal channel having a folded or sinusoidal shape.
