Abstract
A low-noise frequency synthesizer comprises a low-noise oscillator, such as a crystal oscillator, a multiplier, a divider and a phase-locked loop and is adapted to provide an output signal which is a combination of the multiplied and divided frequency. Thus, a large number of frequencies are available as an output in small increments determined by the division ratio of the divider.
