Resonators
Welcome to our web shop where we specialize in vintage and hard to find electronics parts. One of our most treasured items is the resonator. A resonator is a device or system that oscillates at certain frequencies with greater amplitude than at other frequencies. These frequencies are known as resonator resonant frequencies. Resonators are used to generate or select electronic signals of certain frequencies.
In our webshop you will find a wide range of resonators, both in quartz crystal variants and ceramic models. Their unique properties make these parts an essential addition to any electronics project, whether you are a passionate hobbyist or a professional engineer. We are proud to make these hard-to-get parts available to our customers.
Are you looking for a specific resonator? Thanks to our years of experience and extensive network, we may be able to help you find that rare part. Explore our webshop and discover our wide range of resonators and other vintage electronics parts.
- A resonator is a device or system that oscillates at certain frequencies with greater amplitude than at other frequencies. The frequencies at which oscillation occurs are called resonant frequencies. Resonators are used to generate or select frequencies, and can be either mechanical or electronic. Electronic resonators can be made of various materials and technologies, such as quartz, ceramic and surface acoustic-wave (SAW) technology. They are often used in electronic circuits to filter signals, stabilize frequencies or generate oscillations.
- There are several types of resonators, each with their specific characteristics. Quartz resonators are popular because of their excellent frequency stability and low cost. Ceramic resonators have higher resistance to mechanical shock and vibration, but have lower frequency stability. SAW resonators are very compact and have high frequency stability, but are more sensitive to temperature changes. Other types of resonators include the film bulk acoustic resonator (FBAR) and the membrane surface wave (BAW) resonator.
- Resonators are used in a wide range of applications, including clock sources, frequency references, filters and oscillators. They are essential in communication systems, such as cell phones, radios and televisions, as well as in industrial and scientific instruments. Resonators are also used in the automotive sector, for example in keyless entry systems, tire pressure sensors and remote controls. With the increase in the use of wireless technologies and the Internet of Things (IoT), the demand for resonators is growing.
- There are many different types of resonators available, each with their specific characteristics. Quartz resonators are available in a wide range of frequencies, from a few kilohertz to hundreds of megahertz. Ceramic resonators are available in frequencies from a few hundred kilohertz to a few tens of megahertz. SAW resonators are especially suitable for higher frequencies, up into the gigahertz range. The choice of resonator depends on the application, the required frequency stability, sensitivity to temperature changes and mechanical shock, and the available budget.
- The Q factor or quality factor of a resonator is a measure of energy storage in relation to energy losses. The Q factor determines the bandwidth of the resonator; the higher the Q factor, the narrower the bandwidth. A high Q-factor also means higher frequency stability and lower phase noise. The Q factor of a resonator is affected by several factors, such as the material used, physical dimensions, temperature and frequency. For example, quartz resonators generally have a high Q factor, which contributes to their excellent frequency stability.
