An amplifier includes a signal input, a first, second and third amplification path. A coupling element having a first and a second output terminal is coupled to respective input terminals of the first and second amplification paths, and is coupled with a third terminal to an input terminal of the third amplification path. In a first mode of operation the coupling element provides a signal at the first and second output terminals, wherein the signal at the second output terminal comprising a phase shift with respect to the signal at the first output terminal. In a second mode of operation, the coupling element provides a signal at the third output terminal, wherein the provided signal is received at the input terminal and reflected on the first and second output terminals.
