High frequency electromagnetic pulse (EMP) is a major threat to RF front-end electronic devices, and traditional EMP protection devices still have many problems in providing protection. In this paper, Infineon's ESD105-B1-02ELS and gas discharge tube are modelled and simulated, respectively, and their EMP protection characteristics are verified. The transient voltage suppressors have a small power capacity and an unsatisfactory protection effect, and the GDT has a larger power capacity but a long response time, so to combine the advantages and disadvantages of the two, this paper designs a pulse protection device consisting of TVS tubes and GDTs in parallel, with an insertion loss of less than 1 dB and a protection effect of more than 40 dB within 1–2 GHz.
