Components for 433MHz - 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.

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,
