Abstract
Quartz resonator with electrodes that do not adhere to the crystal. Quartz resonator having improved medium-term and long-term stabilities and permitting easier placing on frequency. The resonator comprises, inside a tight housing 1, a condenser formed by two disks 3, 4 made of a dielectric material and separated by a removable ring 2 which determines the spacing between the disks 3 and 4. Electrodes are formed by metallization on the faces of the disks 3 and 4 located opposite a quartz crystal 1 enclosed in said condenser. The spacings between the crystal 1 and the disks 3 and 4 are considerably less than 1 millimeter. Application, for example, in the fields of telecommunications and radars.
