Abstract: An electronic device may include wireless circuitry with delay circuitry coupled to a radio-frequency input of an amplifier over a signal path. Converter circuitry on the signal path may provide a radio-frequency signal to the amplifier based on a baseband signal. An envelope tracking path may couple the delay circuitry to a control input of the amplifier. The delay circuitry may generate a time delay based on a weighting function and a frequency allocation of the radio-frequency signal. The weighting function may be weighted most heavily at a center of the frequency allocation and may decrease as frequency offset increases away from the center frequency. The delay circuitry may apply the time delay between the signal path and the envelope tracking path. The time delay may configure the power amplifier to exhibit optimal radio-frequency performance even when the bandwidth of the frequency allocation is large.
