Abstract
A bi-directional coupler architecture that allows an entire radio frequency coupler to be fully integrated with other circuitry on a single IC substrate. Embodiments of the invention use a lumped component architecture instead of quarter-wave transmission lines to reduce area and limit loss on the primary signal line. In some embodiments, two directional couplers of opposite polarities are implemented at least in part using spiral secondary inductors electromagnetically coupled to a shared primary inductor signal line, thus providing a bi-directional coupler architecture.
