Abstract
In various embodiments, an active vector generator may comprise a vector component switch and a first amplitude adjustment component in parallel with a second amplitude adjustment component. The first and second amplitude adjustment components may operate with different ranges of amplitude. For example, the first amplitude adjustment component may have a full range of amplitude and the second amplitude adjustment component may have a partial range of amplitude. The vector component switch may operate to receive two signals and route the signals to the various amplitude adjustment components based on the relative magnitudes of the two signals. A benefit of having two amplitude adjustment components with selectable signal pathways is that the all the phase states may be obtained but using less robust and expensive amplitude adjustment components.
