Abstract
A radio frequency (RF) transmitter includes a modulation controller that generates a modulation control signal having either a first value or a second value. A driver generates an RF signal based on an upconverted signal, wherein the driver modulates the upconverted signal based on a first modulation signal when the modulation control signal has the first value. A power amplifier generates a transmit signal based on the RF signal, wherein the power amplifier modulates the RF signal based on a second modulation signal when the modulation control signal has the second value.
