Abstract:
1. An active vector generator comprising: a 90° splitter configured to receive an input signal and to output two signals with a relative 90° phase difference; a first inverter switch in parallel with a second inverter switch; a vector component switch; a first amplitude adjustment component in parallel with a second amplitude adjustment component; and a combiner configured to receive two signals and generate a phase-adjusted resultant composite vector; wherein the first and second inverter switches, the vector component switch, and the first and second amplitude adjustment components are electrically connected between the 90° splitter and the combiner, wherein each of the first inverter switch and the second inverter switch are configured to invert a signal based on a desired quadrant of the phase-adjusted resultant composite vector; wherein the active vector generator is configured to adjust the phase of the input signal and generate the phase-adjusted resultant composite vector; wherein the first amplitude adjustment component has a high range of amplitude capability, and wherein the second amplitude adjustment component has a low range of amplitude capability; and wherein the high range of amplitude capability of the first amplitude adjustment component is  to 1, and wherein the low range of amplitude capability of the second amplitude adjustment component is 0 to
