Abstract:
1. An elastic wave device comprising: a first unbalanced terminal and a second unbalanced terminal; a first balanced terminal and a second balanced terminal; a first filter having a first passband and an unbalance/balance conversion function, the first filter having an input electrically connected to the first unbalanced terminal and an output electrically connected to the first balanced terminal and to the second balanced terminal; and a second filter having a second passband with a frequency higher than a frequency of the first passband and an unbalance/balance conversion function, the second filter having an input electrically connected to the second unbalanced terminal and an output electrically connected to the first balanced terminal and to the second balanced terminal, a phase of an electric signal from the first unbalanced terminal to the first balanced terminal in the first filter and a phase of an electric signal from the second unbalanced terminal to the first balanced terminal in the second filter being different from each other, and a phase of the electric signal from the first unbalanced terminal to the second balanced terminal in the first filter and a phase of the electric signal from the second unbalanced terminal to the second balanced terminal in the second filter being different from each other.
