Patent ID: 8837632

Claim:
A vector generator circuit comprising: a splitter to divide an input signal into a first signal and a second signal; a vector switching module to adjust the first signal and to adjust the second signal, the vector switching module comprising a vector component switch to selectively form a first signal path through the vector switching module for the first signal, and to selectively form a second signal path through the vector switching module for the second signal, wherein: the first signal path includes a first switchable phase shift component to adjust phase of the first signal, and a first amplitude adjustment component to adjust amplitude of the first signal over a first range of amplitudes; the second signal path includes a second switchable phase shift component to adjust phase of the second signal, and a second amplitude adjustment component to adjust amplitude of the second signal over a second range of amplitudes; and the first range of amplitudes is different than the second range of amplitudes; and a combiner to combine the adjusted first signal and the adjusted second signal to form a composite output signal, wherein the first range of amplitudes and the second range of amplitudes are each less than a full range of amplitudes to separately form the same phase states of the composite output signal from the first signal and the second signal.
