    Abstract: An RF signal processing device includes multiple first signal receive paths receiving multiple first signals, multiple second signal receive paths receiving multiple second signals and a radio transceiver. The radio transceiver includes a first signal-processing circuit designed for processing the first signals, a second signal-processing circuit designed for processing the second signals, multiple first receive ports coupled to the first signal-processing circuit, multiple second receive ports coupled to the second signal-processing circuit, a first switch and a tunnel device. The first switch is coupled between at least one first receive port and the first signal-processing circuit. The tunnel device is coupled between the first switch and the second signal-processing circuit. The at least one first receive port coupled to the first switch is utilized to receive the first signal or the second signal.

    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.
