Abstract
A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace associated with a first port and a second port. The first port is configured substantially as an input port and the second port is configured substantially as an output port. The coupler further includes a second trace associated with a third port and a fourth port. The third port is configured substantially as a coupled port and the fourth port is configured substantially as an isolated port. In addition, the coupler includes a first capacitor configured to introduce a discontinuity to induce a mismatch in the coupler.
