20160065167 | RECONFIGURABLE DIRECTIONAL COUPLER - This disclosure relates generally to directional couplers. In one embodiment, a directional coupler includes a first port, a second port, a third port, a first inductive element, a second inductive element, a first switchable path, and a second switchable path. The first inductive element is coupled between the first port and the second port, while the second inductive element is mutually coupled to the first inductive element. The first switchable path is configured to be opened and closed, wherein the first switchable path is coupled between a first location of the second inductive element and the third port. The second switchable path is configured to be opened and closed, wherein the second switchable path is coupled between a second location of the second inductive element and the third port. In this manner, a directivity of the directional coupler can be switched between a forward direction and a reverse direction. | 03-03-2016 |
