1. A resonator comprising:
- an inductive element comprising a conductive path routed along a periphery of a volume between an input node and an output node such that the inductive element is a three-dimensional inductor with a length between about 0.5 mm and 20 mm; and
a conductive cavity surrounding the inductive element such that a capacitance is distributed between the inductive element and the conductive cavity along a length of the inductive element.

Abstract
A resonator includes an inductive element and a conductive cavity surrounding the inductive element. In particular, the conductive cavity surrounds the inductive element such that a capacitance is distributed between the inductive element and the conductive cavity. By distributing a capacitance between the inductive element and the conductive cavity, a high quality-factor resonator can be achieved by the resonator with a relatively small form factor.
