Abstract
A disclosed circuit arrangement may include a power detector. A multiplexer circuit may be coupled to the power detector. The multiplexer circuit may include at least two switching sections, one of the switching sections to pass a radio frequency (RF) signal generated based on a first modulation scheme to the power detector and another of the switching sections to pass an RF signal generated based on a second modulation scheme to the power detector.
