1. A linear optimized isolation transformer, comprising:
a figure eight shaped magnetic core having a primary side and a secondary side and a center core member extending from the primary side to the secondary side;
a primary side winding on the primary side of the center core member;
a primary side terminal electrically coupled to the primary side winding;
a secondary side winding on the secondary side of the center core member;
a secondary side terminal electrically coupled to the secondary side winding;
an isolation dielectric placed between the primary side winding and the secondary side winding such that the center core member passes therethrough, and having a shape that fills all of the space between the primary side winding and the secondary side winding that is not occupied by the center core member, the isolation dielectric including a permanent high-Q material selected to maintain a high value isolation independent of pressure differences resulting from operation at different altitudes, the isolation dielectric having an outer diameter that extends beyond the diameters of the primary side winding and the secondary side winding about their peripheries; and
wherein the primary side terminal and the secondary side terminal are positioned on opposing ends of a long axis of the magnetic core.
