Abstract:
1. An electronic circuit comprising: a plurality of duplexers that are coupled to an antenna terminal and have a pass band different from each other; and a plurality of acoustic wave filters that are respectively coupled between the antenna terminal and the plurality of the duplexers, the plurality of acoustic wave filters including a first acoustic wave filter and a second acoustic wave filter, wherein filter characteristics of the first acoustic wave filter of the plurality of the acoustic wave filters are set so as to allow passage of a signal in both a pass band for transmitting and a pass band for receiving of a first duplexer of the plurality of the duplexers that is coupled to the first acoustic wave filter and suppress passage of a signal in both a pass band for transmitting and a pass band for receiving of a second duplexer of the plurality of the duplexers that is different from the first duplexer and that is coupled to the second acoustic wave filter; each of the first acoustic wave filter and the second acoustic wave filter is a band pass filter; and a frequency band included in a pass band of the first acoustic wave filter and a frequency band included in a pass band of the second acoustic wave filter are used for Carrier Aggregation.
