Abstract (en)

[origin: WO2014032889A1] A multiplexer (MUL) having fewer intermodulation products is disclosed. According to the invention, the multiplexer (MUL) comprises an acoustic-wave transmission and/or reception filter (Tx, Rx) as well as blocker electrodes (EL1, EL2) for diverting unwanted frequency components to earth (GND). The blocker electrodes (EL1, EL2) are arranged on the same chip (CH) as the acoustic-wave filter.
