Hello ngks,

It all depends on the power level that you are transmitting. If you transmit power level higher than 1W (+30dBm), then you should take care for protection. You should put your circuit/module in a metal enclosure that will prevent RF radiation. The RF input/output to your system, should be wall-mount RF connectors and for the supply you should use Feed-Through filters.

Assure that the cables are 50-ohm high-quality cables, and that they are short as possible. Fasten the connectors to the walls of the enclosure and fasten the cables to the connectors.

You can ask from a safety specialist to measure the radiation levels near the enclosure and see if these meet the required safety standard.

Hope this helps,

- IR

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
