Abstract: A multi-mixer system includes an amplifier module and a plurality of channels. The amplifier module is arranged for receiving signals from an antenna or antenna arrays to generate a plurality of radio frequency (RF) input signals. The plurality of channels are coupled to the amplifier module, wherein the plurality of channels receive the RF input signals, respectively, and each of the channels includes a mixer for mixing one of the RF input signals with a local oscillating signal to generate a mixed signal. In addition, at least one of the channels includes an interference reduction circuit positioned between the amplifier module and the mixer.

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.
