Abstract: A transmitter configured to support a multimode and a multiband, using radio frequency (RF) digital-to-analog converters (DACs), includes a first RF DAC configured to transmit a first signal in a first frequency band, and a second RF DAC configured to transmit a second signal in a second frequency band different from the first frequency band. The transmitter further includes an impedance controller configured to adjust impedance of one of the first RF DAC and the second RF DAC operating in an impedance matching mode to adjust a frequency range of another one of the first RF DAC and the second RF DAC operating in a data transmission mode.
