A resonator is an electronic component that can generate oscillations at a specific frequency, widely used in fields such as wireless communication, radar, remote controls, etc. There are many common types of resonators, each with specific application scenarios and performance requirements. This article will introduce some popular resonator models and their requirements.
1. Crystal Resonator
A crystal resonator is a resonator that generates oscillations using the piezoelectric effect of a crystal. It has stable frequency, high quality factor, and low temperature drift, widely used in wireless communication, computers, electronic clocks, etc. Common crystal resonator models include HC-49, HC-49S, HC-49U, among which HC-49 is one of the most common models.
The main requirements for HC-49 crystal resonators include frequency stability, quality factor, temperature characteristics, size, etc. Frequency stability refers to the frequency variation range of the crystal resonator within a certain temperature range, usually required to be within a few tens of PPM. The quality factor refers to the energy loss of the crystal resonator, usually required to be above a few thousand. Temperature characteristics refer to the frequency variation of the crystal resonator with temperature changes, usually required to be within a few tens of PPM. Size requirements refer to the external dimensions of the crystal resonator, usually required to meet standard dimensions.
2. Ceramic Resonator
A ceramic resonator is a resonator that generates oscillations using ceramic materials, with characteristics such as low cost, small size, and high temperature resistance, widely used in automotive electronics, home appliances, industrial control, etc. Common ceramic resonator models include CSTCE, CSBTS, CSBL, among which CSTCE is one of the most common models.
The main requirements for CSTCE ceramic resonators include frequency stability, quality factor, temperature characteristics, size, etc. The requirements for frequency stability, quality factor, and temperature characteristics are similar to crystal resonators, but ceramic resonators usually have lower quality factors and frequency stability. Size requirements usually require smaller sizes to meet the needs of miniaturized products.
3. Surface Acoustic Wave (SAW) Resonator
SAW resonator is a resonator that generates oscillations using surface acoustic waves, with high frequency stability, low power consumption, and small size, widely used in wireless communication, radar, sensors, etc. Common SAW resonator models include SAW, SAW-R, SAW-F, among which SAW is one of the most common models.
The main requirements for SAW resonators include frequency stability, bandwidth, temperature characteristics, size, etc. Frequency stability refers to the frequency variation range of the SAW resonator within a certain temperature range, usually required to be within a few tens of PPM. Bandwidth refers to the frequency response range of the SAW resonator, usually required to be above a few tens of MHz. Temperature characteristics refer to the frequency variation of the SAW resonator with temperature changes, usually required to be within a few tens of PPM. Size requirements usually require smaller sizes to meet the needs of miniaturized products.
In general, different types of resonators have different application scenarios and performance requirements, but they all have characteristics such as stable frequency, high quality factor, and low temperature drift. With the continuous development of electronic products, the demand for resonators is also increasing, and it is believed that more new types of resonators will appear in the future to meet the needs of different fields.
