Abstract: An acoustic filter includes a signal input port, a ladder-type filter, a first branch ladder-type filter, a second branch ladder-type filter, and a signal output port. The first branch ladder-type filter and the second branch ladder-type filter are connected in parallel to each other. The signal input port is connected to the ladder-type filter. The ladder-type filter circuit is connected in series to the first branch ladder-type filter and the second branch ladder-type filter. The first branch ladder-type filter circuit and the second branch ladder-type filter are connected to the signal output port.
