Patent ID: 8737531

Claim:
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 2 2 to 1, and wherein the low range of amplitude capability of the second amplitude adjustment component is 0 to 2 2 .
