Radio-frequency front-end circuit and communication device
Abstract:
A radio-frequency front-end circuit includes first and second filters, and first and second band elimination filters. The first filter is connected between an antenna common terminal and a first input-output terminal, and has a first frequency band as a pass band. The second filter is connected between the antenna common terminal and a second input-output terminal, and has a second frequency band as a pass band. The first band elimination filter is connected between the antenna common terminal and a third input-output terminal, and has the first frequency band as a stop band. The second band elimination filter is connected in series with the first band elimination filter between the antenna common terminal and the third input-output terminal, and has the second frequency band as a stop band.
