Compact impedance transformer

A compact impedance transformer comprising:

• a first dielectric substrate;
• a first planar conductor disposed on a top surface of the first dielectric substrate in a first loop extending from a first-first terminal to a second-first terminal;
• a second planar conductor disposed on a bottom surface of the first dielectric substrate in a second loop extending from a first-second terminal to a second-second terminal, wherein the first planar conductor and the second planar conductor are substantially identical and in stacked alignment with the first dielectric substrate residing there between;
• a second dielectric substrate;
• a third planar conductor disposed on a top surface of the second dielectric substrate in a third loop extending from a first-third terminal to a second-third terminal;
• and
• a fourth planar conductor disposed on a bottom surface of the second dielectric substrate in a fourth loop extending from a first-fourth terminal to a second-fourth terminal, wherein the third planar conductor and the fourth planar conductor are substantially identical and in stacked alignment with the second dielectric substrate residing there between.
