[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，
