The receiver filter may be a surface acoustic wave filter, and the transmitter filter and receiver filter are connected via a circulator. The arrangement also comprises a power detecting device for detecting the power into the receiver filter, and the power detecting device provides a feed-back signal to an arrangement for controlling the power out from a power amplifier arranged in front of the transmitter filter.
