Fixed frequency regulation circuit employing a voltage variable dielectric capacitor

Abstract

Frequency regulating apparatus comprising a high power, voltage variable dielectric varactor or capacitor (or ferroelectric voltage variable dielectric capacitor) for use as a control element in the regulation circuit that actively tunes a resonant network to modulate power delivered to a load. The voltage variable dielectric capacitor comprises a substrate having a bottom electrode 33 formed thereon. A dielectric material is disposed on the substrate is a crystallized ceramic material that preferably comprises a barium, strontium, and titanium mixture. A top electrode is disposed on top of the crystallized ceramic material. Methods of fabricating the voltage variable dielectric varactor (capacitor) are also disclosed.
