Josephson Junctions for High Frequency Applications
• AC Josephson Effect: ƒ (2e/h)Vo, 2e/h = 0.4836 GHz/V
V0 from V to mV, f falls into the microwave, mm, sub-mm/THz bands
Generate rf signal of variable frequency controlled by a voltage;
Detect an incoming rf signal;
Measure and detect voltage with extremely high precision.
• Advantages of SC active devices:
extremely low noise,
low power consumption (nWs),
high freq and wide band operation
(due to high-energy gap).

So far…….
• Reproducibility - ok
• Device yield – 100%
• Unshielded operation – possible with the correct RF shielding
• Cost - coming down
• Noise - improving
• Performance – always want better!
• Ic spread – a major focus – 18%
• Formation of a clean single grain boundary - revisiting
