  • Abstract
    A new method of compensating the frequency-temperature dependence of high-and monolithic sapphire dielectric resonators near liquid nitrogen temperature is presented. This is achieved by doping monocrystalline sapphire with Ti/sup 3+/ ions. This technique offers significant advantages over other methods.
