Abstract
An electronic device can include a first group of radio-frequency amplifiers coupled to one or more first antenna(s) disposed at a first end of the device, a second group of radio-frequency amplifiers coupled to one or more second antenna(s) disposed at a second opposing end of the device, a first envelope tracking integrated circuit (ETIC) coupled to the first group of radio-frequency amplifiers, and a second envelope tracking integrated circuit (ETIC) coupled to the second group of radio-frequency amplifiers. The first and second ETICs can be coupled together via a bidirectional input-output voltage path and a feedback voltage path. At least the first ETIC can include a first envelope tracking amplifier, a second envelope tracking amplifier, a voltage converter coupled to an output of the first envelope tracking amplifier, and a feedback controller coupled to an output of the second envelope tracking amplifier and configured to adjust the voltage converter.
