Abstract
A phase-reconfigurable circuit with programmable power splitting for a dual-input power amplifier is provided. The circuit includes an I/Q generator to generate I and Q RF signals from an input RF signal. A first vector-sum phase-shifter processes the I and Q RF signals to produce a first RF output signal. Similarly, a second vector-sum phase-shifter processes the I and Q RF signals to produce a second RF output signal.
