The effect of materials properties on the Q of high Tc helical and coaxial resonators
- 1. AT ampersand T Bell Laboratories, Murray Hill, NJ (USA)
Description
High Tc helical and coaxial resonators have applications in U.H.F. radio receivers. We have employed a variety of techniques to study the superconducting materials used to form such resonators. These include, X-ray diffraction, SEM, density, dilatometry and sedigraph. We have correlated our data with resonator Q and frequency and have determined optimum conditions for highest Q. Our best resonators perform better than their all copper counterparts by a factor of 10 at 77K and at frequencies below 1,000 MHz. We have used these resonators in local oscillators and Butterworth filters in U.H.F. receivers
