Piezoelectric Resonator with Two Layers
Microelectromechanical systems (MEMS) filters have advantages in being able to reduce the size, weight, and power required when used as part of electronic systems such as radios; however, MEMS-type filters have limitations. For example, thickness MEMS-type filters (e.g., thickness-extensional mode...
