【摘要】：無源互調(diào)是空間復雜大功率微波器件設計和衛(wèi)星通信技術中的難題.為了揭示微波器件聯(lián)接扭矩與無源互調(diào)功率電平間的數(shù)學關系,提出了一種快速計算方法.首先,以二項式的形式推導了互調(diào)電壓的求解方法;然后,結(jié)合傳輸線理論建立了單點源無源互調(diào)數(shù)學模型;接著,由實驗測得的微波器件I-V特性計算I-V關系式中的非線性系數(shù),代入點源無源互調(diào)模型來計算不同聯(lián)接扭矩下的無源互調(diào)功率電平;最后,設計了相應的實驗,驗證了點源模型預測三階無源互調(diào)功率電平準確性,解決了微波器件在不同聯(lián)接扭矩下的無源互調(diào)預測難題.
[Abstract]:Passive Intermodulation is a difficult problem in the design of space complex high power microwave devices and satellite communication technology. In order to reveal the mathematical relationship between the connection torque of microwave devices and the passive Intermodulation power level, a fast calculation method is proposed. Firstly, the solution method of Intermodulation voltage is derived in the form of binomial. Then, the mathematical model of single point source passive Intermodulation is established according to the transmission line theory. Then, the nonlinear coefficient in I 鈮，
