A radio heatsink, a radio unit, and a base station are disclosed. According to an embodiment, the radio heatsink (10) comprises a heatsink base (11) and a plurality of heatsink fins (12) extending from a first side of the heatsink base (11), wherein at least one portion (13) of the heatsink base (11) bulges at the first side toward the heatsink fins (12), a recess (14) opening to a second side of the heatsink base (11) that is opposite to the first side is formed at the portion (13), and the radio heatsink (10) further comprises a metal cavity filter (40) integrated with the heatsink base (11). According to another embodiment, the metal cavity filter (40) is separately formed and then inserted into the recess (14).

An electronic device may include a dielectric substrate, an electronic circuit supported by the substrate, for processing data, and a communication unit having an antenna. The communication unit may be mounted to the substrate in communication with the electronic circuit for converting between a first EHF electromagnetic signal containing digital information and a data signal conducted by the electronic circuit. The electromagnetic signal may be transmitted or received along a signal path by the antenna. An electromagnetic signal guide assembly may include a dielectric element made of a dielectric material disposed proximate the antenna in the signal path. The electromagnetic signal guide may have sides extending along the signal path. A sleeve element may extend around the dielectric element along sides of the dielectric element. The sleeve element may impede transmission of the electromagnetic signal through the sides of the dielectric element.

The present disclosure relates to a waveguide gasket arrangement arranged for electrically sealing a waveguide interface between a first waveguide end and a second waveguide end, where the waveguide gasket arrangement comprises a first plurality of electrically conducting members connected to a first common structure along a first circumference. The waveguide gasket arrangement further comprises a second plurality of electrically conducting members connected to a second common structure along a second circumference. For each one of the first plurality of electrically conducting members and the second plurality of electrically conducting members there is a corresponding first sub-plurality of electrically conducting members which are intended to contact a waveguide end, and a second sub-plurality of electrically conducting members which are intended to contact a corresponding intermediate electrically conducting structure that is positioned between the first plurality of electrically conducting members and the second plurality of electrically conducting members.

A shielding element at least partially shields electromagnetic energy radiating from an electronic component. The shielding element includes an inner wall adapted to face the electronic component when assembled. The inner wall includes a material configured to at least partially reflect the electromagnetic energy radiating from the electronic component. The inner wall includes a structure adapted to interfere with at least one of the radiated or reflected electromagnetic energy.

A continuous asphalt mix system for using a microwave heating vessel at the point of production that includes a microwave energy suppression tunnel with one or more mesh flaps for substantially reducing or preventing the leakage of microwave energy from a microwave system, while having a continuous flow of product through the vessel and suppression tunnels. The suppression tunnels are installed on the inlet and/or the outlet side of the system and are sized to suppress leakage.

An electrically- and thermally-conductive gasket includes a planar base and a series of fingers bent out of the plane of the base. The base and the fingers are flexible, allowing the base and the fingers to engage respective matching surfaces on opposite sides of the gasket. The base and the fingers may be parts of a single piece of material, such as a thin metal sheet. The fingers make contact with a surface on one side of the gasket. The fingers may deform separately, allowing good contact to be made even when there is unevenness (non-uniformity) in the surface that they make contact with, or to compensate for the non-uniformity such as non-flatness. Similarly, the base may deform to make good contact with the surface on the side of the gasket opposite the fingers.
