Abstract
The utility model discloses a high-performance 49/S quartz-crystal resonator, which is characterized in that: an auxiliary silver surface is added to each of the front and back silver surfaces of a wafer. The high-performance 49/S quartz-crystal resonator has the advantage that: the parasitic oscillation of lower than -3DB of the conventional high-frequency 49/S resonator can be effectively and greatly reduced to lower than -7DB.
Description
Technical field
The utility model is a kind of low parasitic oscillation, and high performance 49/S quartz-crystal resonator belongs to quartz-crystal resonator development technique field.
Background technology
Existing 49/S resonator electrode design is silver-plated on the quartz wafer two sides through electrode slice, forms the requirement on electric performance that electrode satisfies resonator, high frequency (more than the 20MHZ, down with) parasitic oscillation-below the 3DB.Mainly exist parasitic oscillation high, noise jamming is big, is difficult to detect and adjustment, causes defectives such as crystal mixing use when serious.
Summary of the invention
The utility model exploitation be a kind of 49/S quartz-crystal resonator, its purpose be intended to parasitic oscillation that new design will have high frequency 49/S resonator now from-be reduced to significantly below the 3DB-below the 7DB.
The technical solution of the utility model: its structure is through increasing an auxiliary silver-colored face at the positive and negative silver-colored face of wafer respectively, reaching the beneficial effect of the parasitic oscillation that suppresses resonator.
The advantage of the utility model: can be effectively with the parasitic oscillation that has high frequency 49/S resonator now from-be reduced to below the 3DB-below the 7DB.
Description of drawings
Accompanying drawing 1 is the structural representation that on the positive silver-colored face of wafer, increases an auxiliary silver-colored face.
Accompanying drawing 2 is the structural representations that on the anti-silver-colored face of wafer, increase an auxiliary silver-colored face.
Among the figure 1 is auxiliary silver-colored face.
Embodiment
Contrast accompanying drawing, its structure are to increase an auxiliary silver-colored face 1 respectively at the positive and negative silver-colored face of wafer.Can be effectively with the parasitic oscillation that has high frequency 49/S resonator now from-be reduced to below the 3DB-below the 7DB.
Claims (1)
1. a high performance 49/S quartz-crystal resonator is characterized in that increasing an auxiliary silver-colored face respectively at the positive and negative silver-colored face of wafer.
