High frequency resonant cavity, also known as high-frequency oscillation barrel (concussion barrel), high-frequency oscillation barrel (concussion barrels). Actually high frequency, that is a core component of high frequency machine, high frequency resonant cavity equipped with high-frequency oscillation source device machine --- high frequency tube. article focuses on high-frequency resonator frequency oscillation barrel role and principles.

　　Frequency oscillation frequency resonator barrel (barrel shock), is essentially an LC oscillation circuit. Tube acts as a vibration source by a high frequency. Few boards inside the cavity is substantially equivalent to the capacitor plates. The high-frequency oscillation barrel (concussion barrels) in the middle of the hollow cylinder is equivalent to an inductor. This will form an LC oscillator circuit. Average high frequency oscillation barrel which has a plate can be adjusted distance. That impedance of the capacitor can be adjusted, so that the frequency of the resonant frequency (typically 27.12MHZ, 40.68MHZ, 13.56MHZ). Shell cavity is generally shielded from the effects of ground loops.

　　Must be emphasized that, if the housing of the cavity is of poorer quality, or shielding do not good enough, in the later assembly of successful frequency machine, it may cause leakage of high-frequency ultra-security, multiple potentially harm the human body , or on the office computers, telephones and other office equipment generates high-frequency interference. So in the design cycle oscillation barrel field strength can not make up air ionization intensity.

　　Additional information: In addition to high-frequency resonant cavity square box, coaxial resonator has a few boards out there, there are three boards, five boards. It is also equivalent to ground capacitor plates can fine tune the frequency the same time in the tube cavity, is a positive feedback circuit. Tube should work in the C working condition.

　　Above is about high-frequency resonator frequency oscillation barrel brief introduction, we recommend that customers and friends in the purchase of high-frequency, high frequency machine should also special advisory frequency frequency machine manufacturers in the high-frequency interference shielding aspects of how to do. To avoid trouble on future production.
