COMMUNICATIONS APPARATUSES AND METHODS FOR AVOIDING INTERFERENCE IN COMMUNICATIONS APPARATUS

摘要

A communications apparatus includes a baseband module, a radio transceiver module, a front- end signal processing module and an antenna switch module. The front-end signal processing module is coupled to the radio transceiver module and pre-processes RF signals received from at least one antenna to generate pre-processed RF signals. The front-end signal processing module includes at least a first bandpass filter and a second bandpass filter. A frequency range of a first passband of the first bandpass filter overlaps with a frequency range of a second passband of the second bandpass filter, and the frequency range of the second passband is wider than the frequency range of the first passband.
