Adapting a Cryogenic Sapphire Oscillator for Very Long Baseline Interferometry

Sheperd Doeleman, Tao Mai, Alan Rogers +3

Extension of very long baseline interferometry (VLBI) to observing wavelengths shorter than 1.3mm provides exceptional angular resolution (~20 micro arcsec) and access to new spect…

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…
