Noise properties of HTS Josephson mixers at 345 GHz and operating temperatures at 20 K.

Noise properties of HTS Josephson mixers at 345 GHz and operating temperatures at 20 K.

The authors report on the mixing properties of high-temperature superconductor bicrystal Josephson junctions at 345 GHz and high-operating temperatures. A variable backshort and E-plane tuner enabled the control of impedance matching between the junction and the RF environment. The local oscillator...
