摘要:
多腔徑向耦合構成的輸出系統(tǒng)具有多個頻率點(離散狀態(tài))的寬帶特性,該文從等效電路的觀點出發(fā),給出了多腔徑向耦合輸出系統(tǒng)的等效電路,根據(jù)Kirchhoff定律建立了矩陣方程,導出阻抗矩陣,解出其系統(tǒng)的諧振頻率,鑒于它的多模特點抽出它的典型狀態(tài)推導出它的模式結構,揭示了徑向耦合雙腔的模式分布,反對稱于軸向耦合雙腔(雙間隙腔),它是由2--2模構成。
Abstract:
A multi-cavity output system with radial coupling is provided with broadband characteristics (frequency dispersed distribution in broadband). In this paper, using the method of equivalent circuit, the equivalent circuit of the radial coupling multi-cavity res-onator is presented. After determining the nature of radial coupling holes, applying Kirch-hoffs second law to the circuit and resulting the equation in matrix form, the three resonance frequencies are given by solving impedance matrix obtained. One of three resonance frequen-cies, which is in middle of three is selected to obtain the mode structure and the ratio of gaps amplitude of equivalent voltage of main cavity to vice-cavity. One typical mode distribution is 2ir-ir-2ir in the radial coupling cavities, it is different from part in axial coupling cavities (two-gap extended-interaction resonantors).
