A structure of a high frequency non-reciprocal passive device, such as circulator/isolator and method of installation. The structure includes a substantially rigid lip with cutouts for hot leads to go through. The walls of the cutout are situated in close proximity and symmetrically to the leads. The structure also having mounting holes. The installation process includes a step of putting the structure into a pocket in a carrier wherein a defined amount of a low heat transfer/electrical resistance substance, for example a grease, is located. The size of the lip is larger than the size of the pocket. Therefore the structure is supported on the rim of the pocket, while its portion which is under the lip and having smaller size is located in the pocket. Mounting screws can provide a predetermined pressure to the carrier by the device housing. By this, the lip is provided a reliable grounding in close proximity to the hot leads of the device, while the gap between the bottom of the pocket and the housing of the device is also defined and kept. |
