Embodiments herein relate to a method in a transmitter (501) for enabling a transmission of a signal from the transmitter (12), wherein the transmitter (501) is an out-phasing transmitter. The transmitter (501) generates, in a signal separator (503), two signals with different phases and same amplitude from an input transmission signal. The transmitter (501) then amplifies a first signal of the two signals in a first power amplifier (505) in the transmitter (501 ), and a second signal of the two signals in a second power amplifier (506) in the transmitter (501). The transmitter (501) further obtains, for each of the two amplified signals, an indication of a phase distortion of respective signal of the two amplified signals, and provides, to the signal separator (503), phase distortion information, which is based on the obtained indications. |
