Components for 433MHz - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 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 2010, 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.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

Hi,

I am an ametuer antenna and RF enthusiast. I want to build my own six channel remote controller.

Should at least be having a range of 200mt.

Can any body suggest me Encoder decoder pairs and the corresponding RF transmitter and reciver components?

Prefer to operate at 433MHz.

Please suggest!

Thanks

I have used LINX in the past, and they are okay. You might want to add some 270pF caps on the power supply lines (SRF at ~433MHz), and ESD protection on then antenna input, if you are going in mass production. If you are only building a couple modules, don't worry about it.

Cheers,

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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
