Abstract
This disclosure provides methods, devices, and systems for wireless communications. The present implementations more specifically relate to reducing the power consumption of radio frequency (RF) power amplifiers without sacrificing power efficiency. In some aspects, an RF transmitter may include a modulator, a power amplifier, and a duty cycle controller coupled between the modulator and the power amplifier. The modulator is configured to modulate data onto a carrier signal according to a frequency modulation (FM) scheme. The duty cycle controller is configured to adjust a duty cycle of the FM signal based on a target output power associated with the power amplifier. In some implementations, the duty cycle controller may reduce the duty cycle of the FM signal so that the adjusted duty cycle causes the power amplifier to operate at the target output power. The power amplifier amplifies the adjusted FM signal for transmission over a wireless communication channel.
