Problems solved by technology

[0006] The existing magnetic tuning trap with a global coupling resonant structure uses YIG single crystal ball 3 and coupling ring 2 to form a resonator. This structure is a three-dimensional coupling, which is complicated to assemble and difficult to debug. The direction of the magnetic field is perpendicular to the position of the ball support rod 4, and it is necessary to rotate the ball support rod 4 to adjust the position of the YIG single crystal ball 3 during debugging. Enable multi-channel integration
