subject: healthy - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

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,
