Abstract
A power detector device includes a power detector circuit, a filter circuit, and a calibration circuitry. The power detector circuit is configured to detect a first signal to generate a second signal. The filter circuit is configured to filter the second signal to generate a third signal. The calibration circuitry is configured to determine first signal strength information in response to the third signal, adjust a gain of the power detector circuit to obtain second signal strength information, and combine the first signal strength information and the second signal strength information, in order to calibrate a detection power range of the power detector circuit to be linear.
