There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology.

The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp). The working principle is as shown below.
