What body, the internal chamber wall close contact of the assembly and waveguide, and the assembly were in contact in the internal chamber wall with waveguide
Metal-plated membrane on face.
Further, the both ends of the assembly are extended respectively on the lateral surface of two ring flanges.
Further, the ferritic radial section is the middle square ring structure with square opening.
Further, two switching printed boards are provided with each ring flange, four switching printed boards are between any two
It is in axially symmetric or radial symmetric relative to waveguide.
Further, four switching printed boards are respectively arranged on the medial surface of two ring flanges.
Further, the first threading hole is provided with each switching printed board, is provided with each ring flange
With one-to-one second threading hole of the first threading hole；An at least excitation wire is worn from each ferritic hollow inside
Cross, after its both ends sequentially passes through second threading hole and the first threading hole, be respectively welded in radially right relative to waveguide
In the two switching printed boards claimed.
Further, the dieelctric sheet is made of ceramic materials
Further, the waveguide is rectangular waveguide.
The present invention by plating metal film on the surface for the assembly being made up of two hollow ferrites and dieelctric sheet, then
Assembly after plated film is assemblied in the inner chamber of metallic waveguide, is contacted with the metal inner cavity wall of waveguide so that assembly plates
The metalized surface formed after film is connected with the metal inner cavity wall of waveguide.Coating process ensure that waveguide and assembly
It is in close contact, so as to reduce the required precision of the manufacturing.Heat caused by ferrite is from assembly under high-average power
Metalized surface be transmitted to the metal inner cavity wall of waveguide, so as to improve bicyclic ferrite nonreciprocal phase shifter bear it is flat
Equal power, existing bicyclic nonreciprocal ferrite phase shifter is overcome easy to process and can bear to exist not between high-average power
The problem of getting both.
