    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).

    摘要: A ladder type filter includes series resonators S1˜S4 connected in series between an input terminal In and an output terminal Out, parallel resonators P1˜P3 connected in parallel between the input terminal In and the output terminal Out, a resonator RP connected in series with the series resonators S1˜S4 between the input terminal and the output terminal, the resonator RP having a resonance frequency lower than resonance frequencies of the series resonators S1˜S4, and an inductor Lp connected in parallel with the resonator. According to the present ladder filter, signals having frequencies away from the pass band can be suppressed by an attenuation pole formed by the inductor. It is further possible to suppress the insertion loss in the pass band by the resonator.
