High power variable slide RF tuner |
摘要 |
A high power slide tuning capacitor (200) integrated into a circuit board adapted to function at RF and microwave frequencies. The capacitor (200) is comprised of a dielectric substrate (26) with a cavity (28) cut into a side of the substrate (26); a ground plane (24) mounted on a bottom surface of the dielectric substrate (26); a microstrip patch (22) mounted on a top surface of the dielectric substrate (26) and positioned above the cavity (28); and a movable dielectric stub (30) which engages the cavity (28) such that a variable length of the stub (30) is positioned beneath the microstrip patch (22). The microstrip patch (22) can be coupled to a desired circuit trace (20), effectively forming a shunt capacitor to ground.
