<p>A microwave filter (1) has at least one resonator with a respective cavity (3, 7, 5) and a corresponding conductive or superconductive loading element (27) inside the respective cavity (3, 7, 5). The resonator also has first and second tuning screws (29, 31) at right angles to each other and a mode coupling screw (33) oriented at a 45 degree angle relative to the tuning screws (29, 31). The filter (1) can have a high Q while maintaining a small size.</p> |
