    Abstract: A filter includes a series unit including a plurality of series resonators, and a shunt unit including a plurality of shunt resonators, wherein each of the plurality of shunt resonators is disposed between the plurality of series resonators and a ground. Each of the plurality of series resonators and the plurality of shunt resonators comprises a volume acoustic resonator, and a resonance frequency of a portion of shunt resonators among the plurality of shunt resonators may be equal to a resonance frequency of the plurality of series resonators.

    Abstract: An acoustic resonator filter includes at least one series acoustic resonator, electrically connected between a first port and a second port through which a radio frequency (RF) signal passes, a branch node electrically connected to the at least one series acoustic resonator and having a respective first shunt connection path and a second shunt connection path each extended toward a ground, a first shunt acoustic resonator electrically connected in series with the first shunt connection path, and a second shunt acoustic resonator electrically connected in series with the second shunt connection path, and having a resonance frequency higher than a resonance frequency of the first shunt acoustic resonator. An inductance of the second shunt connection path is higher than an inductance of the first shunt connection path.

    Abstract: A pressure sensor includes a sensor, an elastic support portion, a membrane, and a pressure detector. The sensor is accommodated in a frame of a base substrate. The elastic support portion is elastically connecting the sensor to the frame. The membrane is disposed on a surface of the sensor. The pressure detector is disposed on the membrane and configured to detect a variation in pressure based on a movement of the membrane.
