Abstract:
A radio-frequency front-end circuit includes first and second radio-frequency switches and filters. The first radio-frequency switch includes a first antenna-side terminal and a plurality of first filter-side terminals selectively coupled to the first antenna-side terminal. The second radio-frequency switch includes a second antenna-side terminal and a plurality of second filter-side terminals selectively coupled to the second antenna-side terminal. Some of the filters are multiplexer filters and each includes a common terminal. The common terminals of the filters are coupled individually to some of the first filter-side terminals of the first radio-frequency switch. The second antenna-side terminal of the second radio-frequency switch is coupled to the remaining one of the first filter-side terminals of the first radio-frequency switch.
