ABSTRACT:
A protection arrangement for an electronic device sensitive to electromagic radiation comprises a single printed circuit board which is disposed within a metal casing so that it passes perpendicularly through a metal partition separating an upstream zone in which electromagnetic fields prevail from a screened downstream zone, the board thus having a first part situated in the upstream zone and a second part, which is intended to carry the electronic device, situated in the downstream zone. Electrical signals are conveyed from the upstream zone to the downstream zone by means of conductive lines printed on at least one inner layer of the printed circuit board, and the board is provided with means for filtering the electrical signals comprising surface-mounted components in the vicinity of the metal partition and capacitive elements integrated in the printed circuit board where it passes through the partition.
