Based on transmission line theory and extraction method of active impedance of waveguide slot, a simplified computation method for the leaky-wall ridge waveguide filter is presented in this paper.
基于传输线理论和波导裂缝有源阻抗提取方法，提出了一种脊波导漏壁式滤波器的简化算法。
The active filter acts as an infinite impedance to the external for the fundamental frequency and as a low resistor for harmonic frequencies.
对外电路而言，在基波频率下有源滤波器被控制为无限大阻抗，在谐波频率下被控制为小电阻。
