<p>Frequency regulating apparatus (30) comprising a high power, voltage variable dielectric varactor (16) or capacitor (31) (or ferroelectric voltage variable dielectric capacitor (31)) for use as a control element in the regulation circuit that actively tunes a resonant network (11) to modulate power delivered to a load. The voltage variable dielectric capacitor comprises a substrate (32) having a bottom electrode (33) formed thereon. A dielectric material (34) is disposed on the substrate is a crystallized ceramic material that preferably comprises a barium, strontium, and titanium mixture. A top electrode (35) is disposed on top of the crystallized ceramic material. Methods (20) of fabricating the voltage variable dielectric varactor (capacitor) are also disclosed.</p> |
