ABSTRACT:
A transmission line impedance transformer may include a printed circuit board (PCB) having a dielectric layer and an electrically conductive layer thereon defining a medial interconnection portion, and first and second lateral loop portions extending laterally outwardly from opposing first and second sides of the medial interconnection portion. The PCB also may have first ferrite body receiving openings therein adjacent the first lateral loop portion and second ferrite body receiving openings therein adjacent the second lateral loop portion. The transmission line impedance transformer may also include a first ferromagnetic body extending through the first ferrite body receiving openings to surround the first lateral loop portion, and a second ferromagnetic body extending through the second ferrite body receiving openings to surround the second lateral loop portion.
