Resonators

Resonators are structures or devices used to transfer energy through the medium. The resonator consists of an absorption element, a buffer, and a termination element. They have various types, such as electrical, mechanical, acoustic, and thermal, which can be used in different applications. One of the important types of resonators is ECS-CR2-16.00-B-TR, which is an electrical resonator.

ECS-CR2-16.00-B-TR Application Field and Working Principle

ECS-CR2-16.00-B-TR is a high frequency resonator, which is widely used in wireless communication. It is mainly used in the field of the wireless communication base station, including the 2G, 3G, 4G, and even 5G base station. The system is composed of two matched helical resonators with a coupling factor of 10 dB, an output power of 5 W, and a frequency range of 1.9 – 2.5 GHz.

The working principle of this type of resonator is based on the resonance of the two matched helical resonators. The two resonators are placed in close proximity and a strong RF signal is generated by them. The signal is then alternatingly converted into a transmission signal and a received signal which causes a resonance in the system. This resonance causes the signal to resonate or oscillate in a frequency range that is driven by the signal power level.

In addition, the resonator has the property of suppressing unwanted transmission signals that contain less energy than the desired signal. That is, it can filter unwanted signals to eliminate disturbance, reduce noise, and achieve better signal quality.

Moreover, the two-sided parallel connection makes the resonator structure simple and small in size, so that it can meet various application requirements. In addition, its characteristic suffers little impact from temperature changes.
