摘要: A duplexer includes an antenna terminal, a transmit filter, and a receive filter. The receive filter includes a first sub-filter that includes one or more resonators, and a second sub-filter including a double mode surface acoustic wave (DMS) filter. The second sub-filter is downstream of the first sub-filter relative to the antenna.

摘要: An arrangement includes a substrate, a filter, a first bulk acoustic wave resonator, a second bulk acoustic wave resonator, and a large surface covering. The first bulk acoustic wave resonator includes a first electrode and a second electrode and is arranged flatly on the substrate. The second bulk acoustic wave resonator includes a first electrode and a second electrode and is arranged flatly on the substrate. The large-surface covering includes a metal layer over the substrate. The metal layer is connected to a ground terminal.
