Design and Characterization of a Superconducting Nonlinear Reference Device

December 5, 2003
Author(s)
James Booth, Kenneth Leong, Susan A. Schima, Jeffrey Jargon, Donald C. DeGroot
Abstract ' We describe the design, fabrication, and testing of a nonlinear reference device that has a calculable phase relationship between the fundamental signal and higher harmonic signals in the microwave range. Such a device would be useful for

Nonlinear Microwave Response of MgB 2 Thin Films

December 1, 2003
Author(s)
James C. Booth, Kenneth Leong, S. Y. Lee, J. H. Lee, B. Oh, H. N. Lee, S. H. Moon
Thin films of the newly discovered superconductor MgB 2 show promise for a number of different electronic applications. In order to evaluate the suitability of this new material for communication applications at microwave frequencies, we have measured both

James Booth, Sang Y. Lee, Kenneth Leong, J. H. Lee, J. Lim, H. N. Lee, S. H. Moon, B. Oh
We have measured the temperature dependence of the microwave surface impedance and the nonlinear response of high-quality MgB 2 films on c-cut sapphire at temperatures below 40 K. MgB 2 films with surface resistance (Rs) as low as 0.09 mOhm} at 8 K and 19
