Applications of Josephson Junction SQUIDs (Superconducting Quantum Interference Device) and Arrays

摘要

This is the first Annual Report for an effort to demonstrate the application of SQUIDs (Superconducting Quantum Interference Device) and SQUID arrays to microwave systems. The application considered here is a microwave voltage-controlled oscillator. We report on the circuit design, numerical simulation, experimental design, and fabrication of the device including tests of the monolithic impedance transformer. Predicted available power is approximately 10 nW into a load impedance of ohm.
