Surface wave resonator with reduced acceleration sensitivity

A restrained surface wave resonator system with abated acceleration sensitivity, comprising:

• a pair of metallization layers are stacked on a first major surface of a substrate;
• a first adhesive layer fastens said substrate to a stiffening layer;
• said stiffening layer is attached to a circuit board by a second adhesive, said stiffening layer being composed of a material substantially more rigid than said substrate and said circuit board;
• said substrate having a second major surface with a plurality of horizontal subsurface slotted indentations, said plurality of slotted indentations removing a portion of substrate material from said second surface;
• each of said plurality of slotted indentations being separated by a plurality of structural support members;
• said resonator having a plurality of performance characteristics;
• said resonator, when placed in motion, being ordinarily subjected to a plurality of degrading acceleration sensitivity effects;
• said plurality of degrading acceleration effects further comprising a normal acceleration, an in-plane acceleration and a plurality of flexural deformations;
• said first adhesive layer and said second adhesive layer cooperate with said stiffening layer to isolate said substrate from said plurality of degrading acceleration sensitivity effects;
• and
• said plurality of slotted indentations provide an improved structural rigidity to abate said plurality of degrading acceleration sensitivity effects and maintain said plurality of resonator performance characteristics.
