TRANSVERSELY-EXCITED FILM BULK ACOUSTIC RESONATOR MATRIX FILTERS WITH NONCONTIGUOUS PASSBAND

Abstract:

There are disclosed matrix filters having an input port and sub-filters connected between the input port and respective output ports. Each of the sub-filters includes a ladder circuit with n transversely-excited film bulk acoustic resonator (XBAR) series elements and n-1 capacitor shunt elements, where n, the order of the sub-filter, is an integer greater than 2. The sub-filters having noncontiguous passbands.
