Abstract :
The results of mixing at 61 GHz using weak-link, grain-boundary junctions in Tl2CaBa2Cu2O8 thin films are discussed. Films were prepared using laser deposition of precursor material on MgO substrates followed by high-temperature postprocessing. Mixing experiments were conducted at 75 K, at an IF frequency of 1 GHz, using a bow-tie antenna configuration. The signal-to-noise ratio for the system at the IF frequency was ~104
