Over-the-Air Testing of Cellular Large-Form-Factor Internet-of-Things Devices in Reverberation Chambers

August 4, 2020
Author(s)
Catherine A. Remley, Clive Bax, Edwin Mendivil, Michael Foegelle, John Kvarnstrand, Derek Skousen, David S?nchez-Hern?ndez, Miguel Garcia-Fernandez, Lorien Chang, Elvis Yen, Johnny Gutierrez, Justin Harbour
We demonstrate the applicability of the reverberation chamber for over-the-air testing of power- based metrics for cellular-enabled wireless internet-of-things devices. A recent industry- sponsored round robin illustrates agreement between labs to within

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

… IAPWS formulation for general and scientific use (IAPWS-95) was used. However, for industrial uses such as … for these calculations are faster than those using IAPWS-95 by factors on the order of 100 to 200. The use of IAPWS-IF97 instead of IAPWS-95 for industrial seawater calculations at certain conditions …

Cryogenic photonic resonator with 10-17/s drift

February 11, 2025
Author(s)
Wei Zhang, William Milner, Jun Ye, Scott Papp
Thermal noise is the predominant instability in the provision of ultrastable laser frequency by reference to a cavity. Reducing the thermal-noise limit of a cavity means either making it larger to spread thermal fluctuations, reducing the sensitivity of
