Abstract
A broadband frequency synthesizer including a first local oscillator signal generated in a first phase locked loop. A second local oscillator signal is generated in a second phase locked loop. Third and fourth phase locked loops provide inputs to the second phase locked loop to control the second local oscillator frequency. The system and method provides for small step size tuning while maintaining wide phase lock loop bandwidth.
