ABSTRACT:
A ceramic package is disclosed which comprises a frame member having an ature for accommodating a crystal resonator. The frame member includes mounting clips for supporting the crystal resonator in a desired vibratory mode. A bottom and top lid are then fastened to the frame to enclose the crystal to also enable hermetic sealing in an ultra high vacuum without the use of large deleterious forces.
The package provides a hermetic enclosure enabling improved frequency stability and overall reliability.
