Abstract:
A first filter channel with superior attenuation characteristics for transmission signals and is less susceptible to influence of transmission signals inputted to a transmission SAW filter device, is disposed closer to a transmission terminal, whereas a second filter channel with poor attenuation characteristics in a transmission band and is more susceptible to the influence of transmission signals inputted to the transmission SAW filter device, is disposed farther from a transmission terminal to improve isolation characteristics in a differential mode of a duplexer.
