DEVICE POWER DETECTOR

摘要

A communication device includes a transmitter configured to provide a transmitted output signal, and a power detector configured to receive reference signals from a waveform generator associated with the transmitter, and to receive a portion of the transmitted output signal from the transmitter. The power detector is further configured to compare the reference signals with a digital representation of the portion of the transmitted output signal, and calculate a gain associated with the transmitter based on the comparison. The power detector is also configured to receive, from the waveform generator, a root mean square (RMS) value of the reference signals, and generate an estimate of the output power of the transmitter based on the calculated gain and the root mean square (RMS) value of the reference signals.
