1. A semiconductor device comprising at least one transmit path, the transmit path comprising:
an input node for receiving a digital baseband signal;
digital mixer circuitry coupled to the input node and configured to generate an upconverted digital baseband signal by upconverting a frequency of the digital baseband signal;
Digital-to-Analog Converter, DAC, circuitry coupled to the digital mixer circuitry and configured to generate an analog radio frequency signal based on the upconverted digital baseband signal;
first analog mixer circuitry coupleable to an output of the DAC circuitry;
second analog mixer circuitry coupleable to the output of the DAC circuitry;
a first output node coupleable to an output of the first analog mixer circuitry; and
a second output node coupleable to an output of the second analog mixer circuitry.
