Sj. Penn et al., HIGH-Q DIELECTRIC RESONATORS USING YBA2CU3OX THICK-FILMS AND POLYCRYSTALLINE DIELECTRICS, IEEE transactions on applied superconductivity, 7(2), 1997, pp. 3500-3503
The combination of high Q dielectric resonators and high temperature s
uperconducting (HTS) films offer many advantages in We area of cellula
r and satellite communications. The high cost of single crystal dielec
trics and HTS thin films may be unattractive in certain applications,
Superconducting thick films and polycrystalline ceramic dielectrics of
fer a high performance, low cost alternative to high Q thin film/singl
e crystal dielectric resonators, Results on polycrystalline dielectric
s show that Q's well in excess of 10(5) at 10 GI-Iz and 77 K can be ac
hieved in a design made compact by the use of a HTS thick film shield.
