ABSTRACT:
A precision linear tuning circuit having particular utility to applications employing superconductors in a supercooled environment. Two capacitors, one fixed and one variable, are connected in parallel by an arrangement of shared, concentric electrodes. The variable capacitor includes one electrode and a movable facing dielectric which are tapered such that displacement of the dielectric results in a linear variation in tuning frequency.
