Abstract: An amplifier applicable to an intra-band non-contiguous carrier aggregation (NCCA) band includes a first amplifier circuit and a second amplifier circuit. The NCCA band includes at least a primary component carrier (PCC) channel and a secondary component carrier (SCC) channel not adjacent to each other. The first amplifier circuit receives a first input signal, and generates a first output signal for undergoing down-conversion of one of the PCC channel and the SCC channel. The second amplifier circuit receives at least one second input signal, and generates a second output signal for undergoing down-conversion of another of the PCC channel and the SCC channel. The at least one second input signal received by the second amplifier circuit is provided by the first amplifier circuit according to the first input 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.
