1. A broadside coupled coplanar inductor device comprising:
a first coplanar inductor having a first planar conductor signal path and a first planar return path spaced from the first planar conductor signal path to only a one side in a first direction; and
a second coplanar inductor having a second planar conductor signal path and a second planar return path spaced from the second planar conductor signal path to only one side in a second direction, the first direction being opposite to the second direction;
wherein the first and second conductor signal paths of the first and second coplanar inductors are broadside coupled by principal surfaces of the first and second conductor signal paths directly facing each other,
wherein the first and second planar return paths are not inductively coupled.
