DIPLEXER
A diplexer includes a low-band band pass filter between a common input/output terminal and a low-band input/output terminal and a high-band band pass filter between the common input/output terminal and a high-band input/output terminal, wherein the low-band band pass filter includes LC resonators in...

| description | A diplexer includes a low-band band pass filter between a common input/output terminal and a low-band input/output terminal and a high-band band pass filter between the common input/output terminal and a high-band input/output terminal, wherein the low-band band pass filter includes LC resonators including a first-stage LC resonator to a final-stage LC resonator in order from the common input/output terminal toward the low-band input/output terminal, the high-band band pass filter includes LC resonators including a first-stage LC resonator to a final-stage LC resonator in order from the common input/output terminal toward the high-band input/output terminal, a matching capacitor is between the common input/output terminal and the low-band band pass filter, and the capacitance of a capacitor of the first-stage LC resonator of the low-band band pass filter is smaller than the capacitance of a capacitor of the final-stage LC resonator. |
