Abstract
A high frequency filter includes a filter circuit portion on a first path between first and second signal electrodes, and an additional circuit portion on a second path parallel or substantially parallel to at least a portion of the first path. The filter circuit portion includes series arm resonators, parallel arm resonators, and an inductor on a path connecting a portion or all of parallel arm resonators and a ground. Acoustic wave resonators of the additional circuit portion include first and second electrodes. The first electrodes are connected to the second path. The second electrodes are connected to a connection conductor on a path connecting a portion or all of the parallel arm resonators and the inductor.
