Abstract:

The near zero resistance of superconductors makes it possible to construct resonant circuits with very low losses. Such high Q tunable circuits can provide low noise, narrow band, wide dynamic range tuners for communications equipments. The tuner discussed is a superconductive, tunable, parallel L-C resonant circuit. The inductance and capacitance are varied simultaneously. A tuning range of 171 in frequency has been achieved within a single band - from 1.3 MHz to 23 MHz. Bandwidth can be controlled by coupling control. Qs in excess of 105 were measured. Author
