Abstract
A tuning circuit having a coaxial cavity with a movable toroidal section to effect inductive tuning. The outer conductor is tapered to effect capacitive tuning by movement of the toroidal section axially within the cavity due to varying of the width of the annular space between the outer conductor and the toroidal section.
