Dolph Microwave DH series waveguide terminal devices, including various forms of waveguide matching load, mismatch load, high power load, short circuit, etc. Since a waveguide is physically open for total reflection, it does not have an open circuit, but isrepresented by a one-quarter wavelength short-circuiter. The waveguide matches the load product, and the absorber adopts the bulk absorbing material, which changes the vulnerability of the plate load to vibration and damage, and greatly improves the matching and absorption. Both low power load and high power load are available. Following is the ordering details of high power load as example.
