Abstract :
Two-tone excitation at 3 GHz of hysteretic YBa2Cu3 O7 microwave SQUIDs provide general information on the suitability of such devices for low-power signal processing, e.g. signal detection and frequency conversion. Intermodulation effects, which are expected to characterise the nonlinear dynamic microwave response of HTS films, are also extracted from the data
