Abstract
The invention pertains to a gyromagnetic device such as an insulator, operating at ultra-high frequencies (1-40 GHZ). The assembling of gyromagnetic devices requires high-precision positioning, generally obtained by bonding. In the isolator of the invention, the conducting core and the two ferrite wafers are held by two internal ground plates which form a positioned assembly, one of the plates being provided with tongues which position the parts and which fit into slits in the other ground plate. The assembling is done by stacking, inside the casing, a pressure washer, the magnet, the pre-positioned assembly and the base plate, and by closing the device with a single electric weld.
