Equivalent calculation method for low-pressure discharge threshold of ridge waveguide filter
Abstract
Based on the theory of high frequency breakdown calculation, this paper studies the calculation method of ionization breakdown threshold of ridge waveguide filter under the action of RF field. By comparing with the experimental measurements, the accuracy of the theoretical analysis method of the ionization breakdown of the typical ridge waveguide filter structure is proved. At the same time, the low-pressure ionization breakdown thresholds of different air pressures, structural gaps and working frequencies were calculated, and the action law of each influencing factor was analyzed, and the relationship between breakdown position and electric field distribution was clarified.
