Abstract
An example transmitter includes first and second circuit stages and interface circuits. The first circuit stage is configured to generate modulated signals each having a different carrier frequency from baseband signals. The second circuit stage is configured to generate radio frequency (RF) energy to be radiated by antenna(s). The interface circuits are coupled between the first circuit stage and the second circuit stage. The second circuit stage and the interface circuits are configurable to provide a first mode and a second mode. In the first mode, the second circuit stage provides transmit paths and the interface circuits couple each of the modulated signals to a respective one of the transmit paths. In the second mode, the second circuit stage provides a first transmit path and the interface circuits couple a sum of at least two of the modulated signals to the first transmit path.
