A method of down-converting couples a first high-frequency signal to a first detector and to a second detector. An antenna receives a signal and the received signal is provided to at least the first detector. The high-frequency signal is detected to produce a first detected signal including a first detected high-frequency signal and a demodulated signal. The high-frequency signal is concurrently detected to produce a second detected high-frequency signal. The second detected signal is subtracted from the first detected signal so as to cancel amplitude-modulated noise on a detected signal output.
