ABSTRACT
The harmonic distortion and intermodulation products have been measured for a microstrip amplifier based on a dc superconducting quantum interference device. When the flux bias is adjusted to maximize the gain, in general both second harmonic and a series of odd harmonics are observed. The magnitude of the third harmonic is in good agreement with a simple model. The magnitude of the second harmonic, however, depends critically on the flux bias and is generally a minimum when the gain is slightly less than the maximum value. Similar results are found for the two lowest order intermodulation products. © 2001 American Institute of Physics.

    The critical state of a 1D granular superconductor (modeled as a chain of SQUIDs or, in other words, a 1D Josephson-junction array) is studied on the basis of a system of differential equations for the gauge-invariant phase difference. It is established that the critical state is self-organized....
