Dear Group
I am seeking information on the immunity of commercial equipment to radar at frequencies over 5 GHz. The field strength will be in excess of 300 V/m. There is little information available on the immunity of commercial equipment to radar pulses at these high frequencies and levels. My guess is that equipment will be relatively immune given the bandwidth of IC technology. The rule of thumb for the bandwidth of IC technology is 10 or 20 times the bandwidth. There may, of course, be non linear out of bandwidth responses. >From a search on the web it appears that PCs will not exceed 4 GHz for some time based on the current state of the art 45 µm and 65 µm technology. What is the upper bandwidth of a 3 GHz PC? I would also assume that the high frequency clock is contained within the processor and would be relatively well protected? I would be interested to hear from military test labs that have experience of testing immunity of equipment to pulsed fields up to 18 GHz. How frequently do conventional circuits fail high level EMI testing? Many thanks for any information provided.
