Certain aspects of the present disclosure provide techniques for local oscillator leakage dodging for a radio frequency (RF) transmitter. An example transmitter includes multiple transmit paths, wherein each of the transmit paths comprises a DAC; a mixer coupled to the DAC; and a PLL coupled to the mixer. The transmitter further includes a memory and a processor coupled to the memory. The processor is configured to provide, to the transmit paths, a plurality of first digital baseband signals corresponding to a plurality of RF carriers, when an instantaneous bandwidth of the plurality of RF carriers is different than an occupied bandwidth of the plurality of RF carriers; and provide, to a first transmit path of the transmit paths, one or more second digital baseband signals corresponding to one or more RF carriers, when an occupied bandwidth of the RF carrier(s) matches an instantaneous bandwidth of the RF carrier(s).
