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 trace includes a first main arm, a first connecting trace connecting the first main arm to the second port, and a non-zero angle between the first main arm and the first connecting trace. Further, the coupler includes a second trace associated with a third port and a fourth port. The second trace includes a second main arm.
