Abstract
A method is disclosed for the fabrication of a tunable radio frequency (RF) power output filter that includes fabricating a core body and then forming a plastically deformable metallic shell over the exterior surface of the core body.
Claims16
A method for fabrication of a radio frequency (RF) filter comprising:
- fabricating a core body having an exterior surface capable of receiving a metallic material;
- forming a layer of said metallic material over said exterior surface of said core body, said layer being configured to be plastically deformable;
- and
- plastically deforming said layer of said metallic material to tune said RF output filter to a desired frequency.
