Abstract
Techniques for isolation between filters using inductive coupling cancellation are disclosed. An apparatus includes a first filter including a first plurality of inductors and a second filter including a second plurality of inductors. The first and second filters are implemented physically adjacent to one another. First and second ones of the first plurality of inductors and a first one of the second plurality of inductors are polarized in a first direction, while a second one of the second plurality of inductors is polarized in a second direction opposite that of the first direction. The second one of the second plurality of inductors is physically adjacent to one of the first and second ones of the first plurality of inductors such that magnetic coupling currents induced into one another are canceled.
