Abstract:
In one embodiment, an apparatus includes: a digital baseband circuit to receive a digital baseband signal and output a first digital baseband signal and a second digital baseband signal, the second digital baseband signal comprising a scaled version of the first digital baseband signal; a first transmitter signal path coupled to the digital baseband circuit to process the first digital baseband signal and output a first radio frequency (RF) signal; a second transmitter signal path coupled to the digital baseband circuit to process the second digital baseband signal and output a second RF signal; a first power amplifier coupled to the first transmitter signal path to amplify the first RF signal and output an amplified first RF signal; and a second power amplifier coupled to the second transmitter signal path to amplify the second RF signal and output an amplified second RF signal.
