Abstract
The present invention is directed to a phase shifting arrangement for generating a set of mutually orthogonal signals. In one aspect, the invention provides a system that includes a phase shifting unit for receiving an input signal. The phase shifting unit includes a first phase shift circuit for generating a first output signal phase-shifted by a first amount with respect to the input signal, a second phase shift circuit for generating a second output signal phase-shifted by a second amount with respect to the input signal, and a third phase shift circuit for generating a third output signal phase-shifted by a third amount with respect to the input signal.
