Abstract
A high T(c) Josephson device for high frequency detection applications is being developed, consisting of an YBCO/PBCO/YBCO ramp type junctio n and a broad band log-periodic antenna. In this contribution we prese nt the response of such a device to (near) mm wave irradiation. Shapir o steps have been observed up to very high voltage values - nearly 4 m V at 10 K, at the maximum of the radiation power. The modulation of th e step amplitudes shows very good resemblence with the predictions fro m the Resistively Shunted Junction model.
