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. [ABSTRACT FROM AUTHOR] |
