Abstract: Disclosed is an apparatus comprising means for transmitting a first signal via at least a first switch, a first amplifier, a second switch and a power amplifier, wherein an output of the second switch is connected to a power amplifier path comprising at least the power amplifier, while transmitting the first signal. An input of the first switch and the output of the second switch are switched to switch between transmitting and receiving. A second signal is received via at least the first switch, the first amplifier and the second switch, wherein the output of the second switch is disconnected from the power amplifier path while receiving the second signal.
