Abstract
Apparatus and methods are disclosed related to radio frequency (RF) power detection. One such apparatus includes a directional coupler, an RF switch, and an RF power detector. The RF switch can selectively change coupling between the directional coupler and the RF power detector. This can enable accurate power detection based on a ratio of power levels, without factory calibration or laser trimming.
