Archita Hati (Fed)
Archita Hati is an Electronics Engineer and the calibration service leader of the Phase Noise Metrology Group in the Time and Frequency Division. Her research focuses on precision phase and amplitude noise metrology, designing high spectral purity oscillators and frequency synthesizers, and vibration-induced noise metrology. She is currently involved in the design and development of low-noise X-band oscillators, and a new secondary noise standard for phase and amplitude noise calibrations. She is an Associate Editor for the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, and a member of the International Union of Radio Science (URSI) Commission A and the IEEE International Frequency Control Symposium technical committees.
