Abstract
A tunable cavity resonator includes a housing, a post, and a controllably variable capacitive coupling. The housing defines an interior and has at least one side wall, a first end, and a second end. The post is located within the interior and extends from the first end to the second end. The post and the housing define a resonating cavity. The controllably variable capacitive coupling is disposed in the housing.
