Claim Text:
1. A circuit assembly, comprising: an antenna path, which is configured to be connected to a first antenna; a transmission path; a reception path; a first duplexer, operating with acoustic waves, which connects the transmission and reception paths in each case to the antenna path; a node in the antenna path, wherein the node is connected to a further signal path in which a band pass filter is connected to ground in series via an impedance, and wherein the circuit assembly is configured to suppress an interference signal; and a second antenna path, which is configured to be connected to a second antenna, a second transmission path, a second reception path and a second duplexer operating with acoustic waves, which connects the second transmission and the second reception paths to the second antenna path, wherein the first antenna path is configured to be used for transmitting and receiving signals in a first frequency band and the second antenna path is configured to be used for transmitting and receiving signals in a second frequency band, wherein the first antenna path is connected to a first diversity path configured for receiving signals in the second frequency band, wherein the first diversity path is connected to a third duplexer, which connects the first diversity path to a diversity RX path and a diversity TX path, and wherein the diversity TX path is connected to ground via an impedance such that the diversity TX path is configured to be used for dissipating an interference signal.
