Abstract

A multiplexer (MUL) having fewer intermodulation products is specified. For this purpose, the multiplexer (MUL) comprises a transmit and/or receive filter (Tx, Rx), which operates with acoustic waves, and blocker electrodes (EL1, EL2) for diverting undesired frequency components to ground (GND). The blocker electrodes (EL1, EL2) are arranged in this case on the same chip (CH) as the filter which operates with acoustic waves.
