Abstract
To suppress degradation of characteristics, a high frequency module includes a mounting substrate, a first signal terminal, a second signal terminal, and ground terminals, and a hybrid filter. The hybrid filter is coupled between the first signal terminal and the second signal terminal. The hybrid filter includes an acoustic wave filter having at least one acoustic wave resonator, a first inductor, and a capacitor. The pass band width of the hybrid filter is larger than that of the acoustic wave resonator. A resin layer is disposed on a first principal surface of the mounting substrate. The resin layer covers at least part of the acoustic wave filter. A metal electrode layer covers at least part of the resin layer, and is coupled to the ground terminals. The second inductor is coupled between the hybrid filter and the second signal terminal.
