Abstract: A device has a first switch in a first transmit path coupled between an output of a first DAC (digital-to-analog converter) in the first transmit path and an input of a first baseband filter in the first transmit path. The device also includes a second switch coupled between the output of the first DAC and an input of a second baseband filter in a second transmit path. The second switch is permanently open. The device also has a third switch and a fourth switch. The third switch is coupled between an output of a second DAC in the second transmit path and the input of the second baseband filter. The fourth switch is coupled between the output of the second DAC and the input of the first baseband filter.
