Radio frequency ('RF') absorbing devices used as RF termination devices or free space absorbers, for example, are formed with a planar wafer made of an inorganic thermally conductive material. The planar wafer has a first surface and a second surface opposite the first surface. A metallized resistive film is disposed on the first surface. A metallized reflective heat sink is disposed on the second surface.

High power thermally conductive radio frequency absorbers

A temporary microwave horn antenna coupling device is configured for collecting or injecting quantifiable samples of RF energy. The device comprises single electric field probe mounted at the radiating aperture of a radiating payload. The electric field probe can be oriented at 45 degrees to the horizontal and vertical electric fields of a linearly polarized antenna, or oriented for a single linear polarization to the electric field in a circular polarized antenna. The electric field probe is connected to an attenuator and/or lossy cable for reduced reflections and gradient thermal dissipation.

Single E-probe field aperture coupler

A temporary microwave horn antenna coupling device is configured for collecting or injecting quantifiable samples of RF energy. The device comprises a reduced and highly matched radiating aperture, and a waveguide mounted single electric field probe. The electric field probe can be oriented at 45 degrees to the horizontal and vertical electric fields of a linearly polarized antenna, or oriented for a single linear polarization to the electric field in a circular polarized antenna. The electric field probe is connected to an attenuator and/or lossy cable for reduced reflections and gradient thermal dissipation.
