AI Technical Summary
In existing resonant rod designs, the contact area between the bottom of the resonant rod and the cavity is too large, resulting in poor intermodulation and insufficient stability of the product.
The design incorporates a segmented resonant rod structure with a protruding contact surface at the bottom of the rod, which is locked in place by fasteners to reduce the contact area and improve stability.
This improves the intermodulation yield and stability of the product. The connection stability between the resonant rod and the cavity is enhanced through the cooperation of the boss contact surface and fasteners.
