A coupling circuit for use at microwave frequencies comprising two conductors each having substantially the shape of a W, which conductors are deposited on a substrate in a manner so that the bases of W's oppose one another to form two semi-lumped capacitances of different susceptance, separated by phasing line lengths.

Semi-lumped element coupler

A proximity coupler is provided for high frequency circuits wherein conductors are deposited on a substrate in the shape of a hollow dumbbell intersected by an X. Coupling is provided primarily across sawtoothed shaped gaps in the dumbbell center section and secondarily across a gap formed by spaced parallel connectors in said center section. The parallel conductors have phase delaying loops at opposite ends, and the resulting coupling characteristics of the proximity coupler can be modified by dimensional changes of the loops.
