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: The present invention provides a receiver having an input node, a blocker detector, a translational filter and a low-noise amplifier. The input node is arranged to receive an input signal. The blocker detector is configured to detect if the input signal has a blocker to generate a detection result. The translational filter is configured to filter out an output-of-band blocker of the input signal to generate a filtered input signal at the input node or not filter output the output-of-band blocker of the input signal according to the detection result. The low-noise amplifier is configured to receive the filtered input signal or the input signal to generate an amplified input signal.
