Abstract
An antenna multiplexer comprising an input port for receiving a transmission signal, a common port, an output port, a transmit filter coupled between the input port and the common port, and a receive filter coupled between the common port and the output port. The receive filter includes a first plurality of acoustic wave resonators in a series path between the common port and the output port and a second plurality of acoustic wave resonators each coupled between the series path and ground. None of the second plurality of acoustic wave resonators are coupled to the output port. The first plurality of acoustic wave resonators including a compensation resonator that is coupled to the output port and has a capacitance that is less than an average of the capacitances of the first plurality of acoustic wave resonators. A module comprising the antenna multiplexer. An electronic device comprising the antenna multiplexer.
