Abstract: A co-simulation method using Verilog-a and circuit netlist is adopted for modeling and simulating the electromagnetic pulse (EMP) effects of RF front-end. The low-noise amplifier (LNA) within the RF front-end is modeled via Verilog-a, which is then extended to include the damage effect due to EMP. A standard yet simplified RF front-end of super-heterodyne receiver is constructed using the extended LNA model. The results of S-parameter simulation and transient simulation show that the front-end itself and the extended LNA model can be used to simulate the normal operational functionalities of the receiver. For verifying the extended LNA model’s capability that it can be used to simulate the normal, disturbance and damage effects due to EMP environment, an EMP-dipole antenna coupling channel is modeled via equivalent circuit, the output voltage signals of the circuit are simulated with different EMP-dipole antenna coupling voltage signals as the inputs. In the paper, the EMP effects are categorized into three different levels: non-effect, disturbance, and damage. The corresponding peak voltage thresholds are identified for the RF front-end of super-heterodyne receiver.
