YBa2Cu3O7−δ hot-electron bolometer mixer

Abstract We present an investigation of hot-electron bolometric mixer based on YBa 2 Cu 3 O 7−δ (YBCO) superconducting thin film. Mixer conversion loss, absorbed local oscillator power and intermediate frequency bandwidth was measured at the local oscillator frequency 600 GHz. The fabrication technique for nanoscale YBCO hot-electron bolometer (HEB) mixer integrated into planar antenna structure is described.
