ABSTRACT:
A coaxial coupler unit has an outer conductor fastened to the outside of a first rigid metallic wall on one side of a microwave cavity, and the unit also has an inner conductor having at its front end an axially-fixed, angularly-turnable pin axially extending through a port in such first wall through said cavity to be inserted on the cavity's opposite side in a hole in a second deformable metallic wall bounding such side of the cavity. The pin has helical threads thereon engaging helical threads on the inside of the hole. The pin may, while remaining axially fixed, be angularly turned in opposite directions to displace the deformable cavity wall in opposite axial directions relative to the rigid cavity wall to thereby tune the cavity.
