Description

Technical Field

[0001] The present application relates to the technical field of resonators, and in particular to a resonator. Background Art

[0002] A resonator is an oscillator that can generate a specific frequency. It is used to generate a stable AC signal in a circuit and can be used in wireless communications, radar systems, radio frequency circuits and other electronic devices. The working principle of the resonator is based on the resonance phenomenon, that is, when the vibration frequency of a system matches the natural frequency of the system, a resonance phenomenon will occur, thereby generating an oscillation signal of a specific frequency.

[0003] Resonators are usually divided into mechanical resonators and electronic resonators. Mechanical resonators use the natural frequency of the mechanical system to produce resonance. For example, quartz crystals or ceramic resonators are usually used to generate oscillation signals of specific frequencies. Electronic resonators use components such as inductance, capacitance, and resistance in the circuit to produce resonance. The most common electronic resonator is the LC resonator, which is composed of an inductor and a capacitor. When the natural frequencies of the inductor and capacitor match, resonance occurs.

[0004] Capacitors can achieve advantages such as higher data rates, higher signal integrity and noise immunity. However, since the insulating substrate of the capacitor is limited by material constraints, it is difficult to achieve a higher isolation voltage, which in turn leads to poor high-voltage resistance of the resonator.
