Abstract
A wireless communications device may include a controller configured to, in a calibration mode, obtain a first output value of a first power detector after setting a first power amplifier to a first gain and obtain a second output value of the first power detector after setting the first power amplifier to a second gain, wherein the controller may estimate, in a normal mode, output power of a first antenna from an output value of the first power detector, based on a correction coefficient calculated using the first output value and the second output value.
