    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： A duplexer is described herein. The duplexer includes a transmission branch configured to allow passage of signals in a transmission band. The duplexer also includes a reception branch configured to allow passage of signals in a reception band. The duplexer also includes a band rejection filter in the transmission branch configured to produce a short circuit to an electrical ground in a stopband. The stopband at least partially overlaps the reception band.

    摘要： A component includes a filter having a first structure and a second structure. The component also includes a substrate on which the first and second structures are arranged. The first structure has an approximately uniform layer thickness and an approximately uniform composition. The second structure has an approximately uniform layer thickness and an approximately uniform composition. At least one of the layer thickness or composition of the first structure differs from the layer thickness or composition of the second structure.
