Abstract
The disclosure relates to systems and methods for fabricating printed circuit board (PCB) based transformers and/or coreless PCB-based circuits containing one or more coil inductor(s). More specifically, the disclosure is directed to systems and methods for fabricating PCB-based transformers and/or inductors having concentric or eccentric (non-concentric) continuous or concatenated coil architecture.
Claims6
A printed circuit bias-T circuit board (BTCB) comprising:
- a signal transmission line;
- an input port disposed at a first lateral end of the signal transmission line;
- at least one capacitor interposed between the input port and the transmission line;
- an output port disposed at a second lateral end of the signal transmission line;
- and
- an eccentric conical winding element having a bias feeding end and a termination end,
- wherein the eccentric conical winding element comprises a plurality of non-concentric tear-drop shaped helical windings of increasing turn ratio, or decreasing turn ratio, from the bias feeding end to the termination end, and
- wherein the termination end is operably coupled to the signal transmission line.
