Patent ID: 8406707

Claim:
A system for generating local oscillator (LO) signals for a harmonic rejection mixer, the system comprising: a divide-by-N frequency divider configured to divide a reference frequency signal by a value N and provide an output signal; a divide-by-three frequency divider configured to receive the output signal of the divide-by-N frequency divider and divide the output signal into three phase-offset signals; and a phase recombiner configured to receive the three phase-offset signals and provide four phase-offset signals, the phase recombiner including a first plurality of mixer elements and a first plurality of summation elements, each mixer element configured with at least one modulator weight and configured to mix at least one of the three phase-offset signals with the at least one modulator weight, the first plurality of summation elements summing outputs of the first plurality of mixer elements to provide the four phase-offset signals.
