Abstract
One configuration of the present invention is a radio frequency transformer board that has a planar dielectric substrate having a first surface, an opposite second surface, and a transformer. The transformer includes a first elongate conductor disposed on the first surface and having a first end and a second end, a second elongate conductor disposed on the second surface and having a first end and a second end. The first end of the first conductor and the second end of the second conductor are disposed proximate an edge of the substrate and spaced apart from one another along the edge. The second end of the first conductor and the first end of the second conductor are electrically shorted to one another proximate the edge of the substrate.
Claims20
A radio frequency transformer board comprising:
- a planar dielectric substrate having a first surface and an opposite, second surface;
- an unbalanced transformer comprising a first elongate conductor disposed on said first surface and having a first end and a second end, a second elongate conductor disposed on said second surface and having a first end and a second end, said first end of said first conductor and said first second of said second conductor disposed proximate one edge of said substrate and spaced apart from one another in a plane of said substrate;
- and
- an electrical short joining said second end of said first conductor and said first end of said second conductor proximate said edge of said substrate.
A radio frequency transformer board having a planar dielectric substrate having a first surface, an opposite second surface, and a transformer, said transformer including a first elongate conductor disposed on the first surface and having a first end and a second end, and a second elongate conductor disposed on the second surface and having a first end and a second end, wherein the first end of the first conductor and the second end of the first conductor are spaced apart from one another proximate an edge of the substrate, and the first end of the second conductor and the second end of the second conductor are spaced apart from one another at the same edge of the substrate.
