Low frequency ball grid array resonator

A ball grid array resonator for use as, for example, a high "Q" inductive element in the tank circuit of a voltage controlled oscillator. The resonator comprises a ceramic substrate including opposed top and bottom surfaces, each having a continuous strip of conductive material formed thereon and, in one embodiment, at least two conductive vias which extend through the substrate and electrically interconnect the respective strips of conductive material to define a continuous and elongate path or transmission line for an RF signal. The respective strips of conductive material may be spiral-shaped, hook-shaped, serpentine-shaped, or otherwise suitably shaped depending upon the desired application. Conductive balls/spheres on the bottom surface define RF signal input/output pads and ground pads adapted for electrical connection to the printed circuit board or substrate of, for example, a voltage controlled oscillator.
