Abstract: An electronic device may include wireless communications circuitry, control circuitry, and sensor circuitry. The wireless communications circuitry may include amplifier circuitry that amplifies radio-frequency signals using on a bias voltage to generate amplified radio-frequency signals transmitted over an antenna. Power supply circuitry may generate the bias voltage based on an envelope mapping setting and an envelope signal associated with the radio-frequency signals. The sensor circuitry may generate sensor data that characterizes the performance of the wireless communications circuitry and provide the sensor data to the control circuitry. The control circuitry may use the provided sensor data to generate control signals for the power supply circuitry. The control signals may adjust the envelope mapping setting of the power supply circuitry.

Abstract: Systems and method to improve performance of a radio frequency system while operating in compliance with wireless transmission regulations are provided. One embodiment describes a radio frequency system including an antenna that wirelessly transmits an analog electrical signal at a transmission frequency and receives a first network signaling value from a wireless network. The radio frequency system further includes a controller that determines operational constraints on the radio frequency system based on a region of operation; determines a second network signaling value based on the operational constraints, in which the second network signaling value overrides the first network signaling value; determines operational parameters based on the second network signaling value; and instructs the radio frequency system to implement the operational parameters to facilitate the radio frequency system operating in compliance with the operational constraints.
