A Case Study of Medical Device Wireless Coexistence Evaluation

October 1, 2020
Author(s)
Mohamed Al-Kalaa, Joshua Guag, Seth Seidman, Yao Ma, Jason Coder
This article aims to provide a narrative for addressing wireless coexistence in medical devices to help medical device developers, test engineers, and regulatory affairs personnel throughout the device life cycle. Accordingly, we present a case-study

A Cryogenic Quantum-Based RF Source

September 10, 2020
Author(s)
Justus A. Brevik, Alirio De Jesus Soares Boaventura, Manuel C. Castellanos Beltran, Christine A. Donnelly, Nathan E. Flowers-Jacobs, Anna E. Fox, Peter F. Hopkins, Paul D. Dresselhaus, Dylan Williams, Samuel P. Benz
We performed a preliminary calibrated measurement of the output power of a Josephson arbitrary waveform synthesizer up to 1 GHz. We present the results and measurement procedure for generating quantum-based signals using an array of Josephson junctions

Uncertainty of Large-Signal Measurements Under Variable Load Conditions

August 8, 2020
Author(s)
Konstanty Lukasik, Jerome Cheron, Gustavo Avolio, Arkadiusz Lewandowski, Dylan Williams, Wojciech Waitr, Dominique Schreurs
We thoroughly investigate the uncertainty of large-signal measurements when load conditions at the fundamental frequency change. In particular, we evaluate uncertainties of the incident a2 and scattered b2 frequency-domain spectra. They are of particular

Energy-Efficient SWIPT-Empowered D2D Mode Selection

April 17, 2020
Author(s)
Hamid Gharavi
While mode selection has been envisioned as the most cost-effective way to address the interference issue in Device-to-Device (D2D) communications, existing works have been largely conducted without consideration of the energy depletion of devices. In this

Microwave Modeling and Characterization of Superconductive Circuits for Quantum Voltage Standard Applications at 4 Kelvin

February 10, 2020
Author(s)
Alirio De Jesus Soares Boaventura, Dylan F. Williams, Richard A. Chamberlin, Jerome G. Cheron, Anna E. Fox, Paul D. Dresselhaus, Peter F. Hopkins, Ian W. Haygood, Samuel P. Benz
We developed a cryogenic multiline thru-reflect-line (TRL) calibration kit for microwave characterizing of superconductive circuits used in the Josephson arbitrary waveform synthesizer of the national institute of standards and technology (NIST). We also

RF Dataset of Incumbent Radar Signals in the 3.5 GHz CBRS Band

December 17, 2019
Author(s)
Raied Caromi, Michael R. Souryal, Timothy Hall
This Radio Frequency (RF) dataset consists of synthetically generated waveforms of incumbent 3.5 GHz radar systems. The intended use of the dataset is for developing and evaluating detectors for the 3.5 GHz Citizens Broadband Radio Service (CBRS) or

1 GHz Waveform Synthesis with Josephson Arrays

July 31, 2019
Author(s)
Christine A. Donnelly, Justus A. Brevik, Nathan E. Flowers-Jacobs, Peter F. Hopkins, Paul D. Dresselhaus, Samuel P. Benz
For the first time, we synthesize single- and multiple-tone waveforms at gigahertz frequencies from arrays of Josephson junctions and demonstrate quantum-locked operation over a range of experimental input parameters. We first use a lumped-element circuit

Machine Learning in a Quality Managed RF Measurement Workflow
