Transmission line impedance transformer and related methods
First Claim
1. A transmission line impedance transformer comprising:
- a printed circuit board (PCB) comprising at least one dielectric layer and at least one 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, said PCB also having a first plurality of ferrite body receiving openings therein adjacent the first lateral loop portion and a second plurality of ferrite body receiving openings therein adjacent the second lateral loop portion;
at least one first ferromagnetic body extending through the first plurality of ferrite body receiving openings to surround the first lateral loop portion; and
at least one second ferromagnetic body extending through the second plurality of ferrite body receiving openings to surround the second lateral loop portion.

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.
