摘要： A duplexer includes an antenna terminal, a first filter connected to the antenna terminal, a second filter that has a passband at a high-frequency side of the first filter and is connected to the antenna terminal, and a resonance circuit that is connected between the second filter and the antenna terminal and includes a first inductor and a first capacitor connected in parallel. Assuming that a passband frequency of the first filter ranges from f1Low to f1High (f1Low˜f1High) and a passband frequency ranges from f2Low to f2High (f2Low˜f2High), the resonator has a resonance frequency fr satisfying: fr=(f2Low˜f2High)±(f1Low˜f1High), or fr=2(f1Low˜f1High)±(f2Low˜f2High).
