Реферат: An apparatus includes multiple signal paths for signal transmission, and control circuitry. The multiple signal paths include a first signal path and a second signal path. The first signal path is configured to convert a digital baseband signal to a first radio frequency (RF) signal having a first frequency and a first gain. The second signal path is configured to convert a digital baseband signal to a second RF signal having a second frequency and a second gain, wherein the second gain is less than the first gain. The control circuitry is coupled to the plurality of signal paths and is configured to receive one or more control signals to enable selective activation of at least one signal path of the plurality of signal paths.
