  • Patent number: 12381305
    Abstract: Quarter-wavelength switchable directional coupler architectures and methods that that use intermediate terminated states during directional mode-switching events to prevent generation of reflection coefficients that cause spur generation. A first embodiment of the invention utilizes existing circuitry within a quarter-wavelength switchable directional coupler but alters the conventional mode-switching sequence by adding new stage sequences to effectuate intermediate terminated states to mitigate or prevent spurs. A second embodiment of the invention modifies existing circuitry within a quarter-wavelength switchable directional coupler by adding a cross-coupled intermediate-stage termination circuit, and alters the conventional mode-switching sequence by adding new stage sequences to effectuate intermediate terminated states to mitigate or prevent spurs.
