Abstract:
A receiver apparatus includes a receiver path and a blocker detection path. The receiver path includes a down-converting stage. The blocker detection path includes a sensing circuit and a blocker detection circuit. The sensing circuit is arranged to sense a received radio frequency signal which has not yet been processed by the down-converting stage and generate a sensed signal accordingly. The blocker detection circuit is arranged to detect existence of a blocker signal according to the sensed signal and generate a blocker detection result indicative of the existence of the blocker signal when receiving the sensed signal.
