Abstract
Multi-output electromagnetic couplers configured to detect multiple frequencies simultaneously, and devices and systems including same. In one example a multi-output electromagnetic coupler includes a main coupler transmission line extending between and electrically connecting an input port and an output port, a first coupled line section configured to couple electromagnetic power in a first frequency band from the main coupler transmission line to provide a first coupled output signal at a first coupled port, and a second coupled line section configured to couple electromagnetic power in a second frequency band from the main coupler transmission line to provide a second coupled output signal at a second coupled port simultaneously with the first coupled output signal being provided at the first coupled port.
