Abstract:
An arrangement for reducing interference of radio frequency signals in a transceiver summing part, comprising:a conductive housing; andat least one common transmission line in the summing part for carry at least two different signals, whereinthe housing of the summing part is arranged to function as the only ground plane for the transmission line, without a separate ground plane being electrically coupled to the transmission line and arranged on a printed board, in order to reduce intermodulation distortion of signals which arises in the summing part, whereinthe summing part comprises the printed board including the at least one common transmission line for at least two different signals; andin order to reduce intermodulation distortion of signals, which arises in the summing part, the printed board is one-sided; andthe transmission line is formed on the one side.
