#184857 - Pi Filters Responding to: ???'s previous message |
Kai Klaas said:
Make the ground plane of pcb part of the Faraday cage and bond it to the cage at as many points as possible. Do you mean the board inside the faraday cage or the board carrying the faraday cage or both? The signals passing the Faraday cage should do it via pi-filters, with their caps at both sides (inside and outside) referenced to the ground plane directly at the Fraday cage. The signals are fed through the Faraday cage via ferrites or resistors. Make tiny holes in the Faraday cage, where the signals enter or leave it and place the series element of pi-filter directly under the barrier. do you have typical values for the R and Cs? Thanks Dear Kai |
