Abstract
Radio transmitters providing an analog signal with both radio frequency (RF) and baseband frequency information are disclosed herein. In certain embodiments, a transmitter for an RF communication system includes a radio frequency digital-to-analog converter (RFDAC) that outputs the analog signal with two bands of content. In particular, the analog signal includes a first band on content at RF frequency and representing the RF signal for transmission, and a second band of content at baseband frequency and representing baseband information such as the envelope of the RF signal.
