Abstract :
We present experimental results on microwave intermodulation measurements on a High T/sub c/ Superconducting band-reject microstrip resonator which exhibits unconventional 2:1 intermodulation products. We discuss unusual features of this 2:1 behavior that are uncovered by detailed frequency swept and unbalanced power measurements. We also introduce a phenomenological theory which arises from a nonlinear inductance of the form L=L/sub 0/+/spl alpha/|I| which quantitatively describes the observed response.
