Title
A High Attenuation Electromagnetic Pulse Protector With Gdt, Mov And Parallel Coupled Bpf On High Thermal Conductivity Substrates
Abstract
An alternative approach for robust electromagnetic pulse (EMP) protection circuit was proposed by using a parallel coupled band-pass filter (BPF) with high thermal conductivity AlN substrate in between with a traditional gas discharge tube (GDT) and fast response metal oxide varistor (MOV). This proposed configuration can suppress slow as well as fast voltage surges. The fabricated BPF with a center frequency of 2.5 GHz on the high thermal conductive (180~200 W/m·K) AlN substrate could efficiently suppress high power over voltage surge. Through the purposed cascade protection configuration, it is observed that 6KV ESD fast introduced pulse (5 ns/50 ns) and 4 KV lightning surge pulse(1 μs/50 μs) were attenuated to 511V and 396 V, respectively, and that is capable to be applied to an EMP protection circuit in the front end of a linear amplifier applications.
