Acoustic wave devices and modules with acoustic wave devices

An acoustic wave device comprising:

• a first filter;
• a second filter;
• a ground terminal;
• a common terminal connected to an output side of the first filter and an input side of the second filter;
• a first filter terminal connected to an input side of the first filter;
• a second filter terminal connected to an output side of the second filter;
• a ground electrode connected to a ground metal body comprising the ground terminal or a wiring connected to the ground terminal;
• an input side ultrasonic delay electrode connected to an input side metal body arranged in parallel with the ground electrode on one side of the ground electrode and includes the first filter terminal or a wiring connected to the first filter terminal;
• and
• an output side ultrasonic delay electrode connected to an output side metal body arranged in parallel with the ground electrode on another side of the ground electrode and includes the second filter terminal or a wiring connected to the second filter terminal, wherein the first filter comprises a transmitting filter comprising two series capacitors connected in series between the input side metal and the input side ultrasonic delay electrode and a parallel capacitor connected in parallel between two series capacitors.
