Ultra stable and very low noise signal source using a cryocooled sapphire oscillator for VLBI

Nitin R. Nand, John G. Hartnett, Eugene N. Ivanov +1

Here we present the design and implementation of a novel frequency synthesizer based on low phase noise digital dividers and a direct digital synthesizer. The synthesis produces tw…
