ABSTRACT:
Transformer configurations especially useful in the microwave frequency range. A reliable physical center-tap is achieved by the interposition of a stub at the center of an elongated member which provides electrical contact with a reactive impedance. The circuit formed thereby allows the reflection of an r.f. short circuit to the center of the elongated portion without attendant fabrication thereon. A loop configuration for the remaining coupling means allows adjustability of electromagnetic coupling which is less sensitive to spacing of primary and secondary than the common parallel configuration.
