Abstract: A phase-reconfigurable circuit for a dual-input power amplifier is provided. The circuit includes an envelope detector configured to process an envelope of an RF input signal into an envelope signal. A first vector-sum phase-shifter and a second vector-sum phase-shifter processes an in-phase and a quadrature-phase version of the RF input signal with the envelope signal to produce a first differential output signal having a dynamically-modulated phase difference with a second differential output signal.
