Abstract
A directional coupler having coupling variability at separate portions of an operational frequency band. A frequency selective coupler comprises an input port, an output port, a coupled port, a termination port, a first RF filter coupled to the coupled port, and a second RF filter coupled to the termination port. The first and second RF filters yield a first coupling value at a first portion of the operational frequency band of the coupler and a second coupling value at a second portion of the operational frequency band. The first portion of the band corresponds to a range of frequencies at which higher coupling for the coupler is desired and greater loss in the signal is tolerable. The second portion of the band corresponds to a range of frequencies at which lower coupling for the coupler is tolerable and lower loss in the signal is desirable.
