Description

technical field [0001] The invention relates to a resonator device based on MEMS technology and a manufacturing method thereof in the field of wireless communication, in particular to a MEMS resonator and a manufacturing method thereof. Background technique [0002] Communication science is the cornerstone of the high-tech information society and the core of the high-tech information industry. Wireless communication is one of the most important methods to realize communication science. The quality and performance of the communication system are directly determined by the quality of the wireless communication technology. A wireless communication system is mainly composed of an input modulator, a sending device, a receiving device, an output demodulator, and a channel. The reliability and effectiveness of its information communication mainly depend on the accuracy, phase noise, and system stability of the system's frequency oscillator. The input modulator, transmitter, receiv...
