Abstract: A filter arrangement (EFM) comprises a first terminal (T1) arranged for handling duplex radio antenna feeder signals for at least two transceiver modules (10, 20), a second terminal (T2) arranged for handling at least duplex signals for a first transceiver module (10), a third terminal (T3) arranged for outputting a first multi carrier power amplifier system input signal, said input signal representing a transmit signal from said first transceiver module (10), a fourth terminal (T4) arranged for receiving a multi carrier power amplifier system output signal, said output signal comprising an amplified representation of the transmit signals from said at least two transceiver modules, and wherein said first and said second terminal (T1, T2) are connected via first single filter means (RX), said second and said third terminal (T2, T3) are connected via second single filter means (TX1), said fourth and said first terminal (T4, T1) are connected via third single filter means (TX2).
