Analytical method of electromagnetic susceptibility for radio frequency receiver at behavior level

Based on simplified Volterra model, an approach to the simulation analysis of electromagnetic susceptibility (EMS) for radio frequency (RF) receiver at behavior level was presented. Third order simplified Volterra model was adopted to analyze receiver EMS. A general criterion for EMS was proposed according to EMS response characteristics in frequency domain and then flow charts for calculating susceptibility thresholds by simulation were given. This approach is superior to the previous receiver EMS analysis which mainly relies on experiments but lack of simulation analysis. Take dual frequency GPS receiver interfered by continue wave as an example for in-band and out-of-band (including image frequency and intermodulation) susceptibility thresholds calculation. Simulation results show that the proposed method is not only valid and effective, but also reduces internal storage and simulation time which is suitable to RF receiver EMS analysis and practical in engineering and technology field.
