Abstract:
1. A multicarrier transmitter having a first mode, in which the transmitter is configured to transmit a first component carrier signal modulated onto a first carrier by using a first local oscillator (LO) signal, and a second mode, in which the transmitter is configured to transmit the first component carrier signal modulated onto the first carrier and a second component carrier signal modulated onto a second, different carrier by using a second LO signal, wherein the multicarrier transmitter is coupled to a controllable oscillator and configured to adapt a frequency of an LO signal output by the controllable oscillator dependent on the multicarrier transmitter being activated in the first mode or the second mode; wherein in the first mode, the first LO signal is output from the controllable oscillator; and wherein in the second mode, both the first LO signal and the second LO signal are output from the controllable oscillator at different times; wherein the frequency of the LO signal is controlled via a control signal for the controllable oscillator; wherein the multicarrier transmitter comprises means for adapting the control signal in order to adapt the frequency of the LO signal; wherein the multicarrier transmitter comprises the controllable oscillator and a combination element arranged at the control input of the controllable oscillator; and wherein the combination element is configured to add a control signal for the controllable oscillator and an offset signal output by the multicarrier transmitter for adapting the frequency of the LO signal.
