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.
Abstract:
A duplexer includes an antenna terminal, a transmission amplifier terminal and a reception amplifier terminal. The transmission amplifier terminal is coupled to the antenna terminal via a transmission filter. The reception amplifier terminal is coupled to a reception filter and the reception filter is coupled to the antenna terminal via a band-stop filter.

Abstract:
A capacitor having improved linear properties is provided. The capacitor is compatible with manufacturing processes of components which function using BAW. The capacitor comprises a first and a second electrode (E1, E2) in a first electrically conductive layer and a third electrode (E3) in a second electric layer. A dielectric layer (DL) is arranged between the electrically conductive layers. The first electrode (E1) and the second electrode (E2) are the terminal electrodes of the capacitor.
