A system for generating local oscillator (LO) signals for a quadrature mixer includes an oscillator configured to provide a reference frequency signal, at least one frequency divider configured to divide the reference frequency signal into three offset phase signals, a first summing circuit configured to generate two nominal 90 degree offset phase signals from the three offset phase signals, and a second summing circuit configured to generate at least two amplitude-corrected 90 degree offset-phase quadrature signals. |
