Abstract: A communication device with a power detection scheme is disclosed. The communication device includes a transmitter for transmitting an RF signal, a demodulator for demodulating the RF signal by utilizing a phase-modulated (PM) signal provided from the transmitter to generate a demodulated signal, a loopback circuit coupled between the transmitter and the demodulator for transmitting the RF signal and the PM signal from the transmitter to the demodulator when the power detection scheme is enabled, and a power detector for detecting power of the demodulated signal.
