Front-end circuit with increased flexibility in the arrangement of the circuit components

摘要

Front-end circuit (FES), comprising a first module (M1) having an antenna terminal (AAM1), a diplexer (DI) and a first duplexer (DU1), a second module (M2) with a second duplexer (DU2), - A first signal path (SP1) and a second signal path (SP2), wherein the diplexer (DI) has an antenna connection, a low-pass filter with a low-pass connection and a high-pass filter with a high-pass connection, the first duplexer (DU1) has a transceiver connection, a transmission connection and a reception connection, the second duplexer (DU2) has a transceiver connection, a transmission connection and a reception connection, the transmission reception connection of the first duplexer (DU1) via the first signal path (SP1) to the high-pass connection of the diplexer (DI) and the transmission-reception connection of the second duplexer (DU2) via the second signal path (SP2) to the lowpass Connection of the diplexer (DI) is connected, further comprising - Another bandpass filter having an input terminal and an output terminal, wherein the input terminal of the further bandpass filter is connected to the high-pass connection, the further band-pass filter works with surface acoustic waves, with guided bulk acoustic waves or with bulk acoustic waves, and - The other bandpass filter lets satellite receive signals pass.
