Abstract

We report on NIST’s development of Josephson junction-based programmable reference sources to synthesize quantum-accurate, spectrally-pure waveforms for characterizing and improving next generation communication devices and systems. The goal is to provide reference sources that together span the entire radio frequency (RF) band, equivalent to 7 orders of magnitude in frequency (20 kHz - 300 GHz). To synthesize waveforms in the microwave frequency band, we are extending the existing Josephson arbitrary waveform synthesizer (JAWS) technology that is used for ac voltage metrology at audio frequencies (
