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...

RF transmitter and receiver selection - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 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 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. 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 there, First of all I applogize if I've posted this in the wrong index.

I'm brand new to the world of RF and I'm attempting a design project I've had in my head for a while now. I'm getting overwhelmed while trying to source/specify the correct receiver/transmitter combo for the job.

This is a household application (not just a garage door opener, need range in the entire house/multi levels). Ridiculously low data rate needed.

What frequency range should I be looking at? What type of modulation scheme is recommended? Are there household frequency ranges?

I'm looking for an "off the shelf", ie. digikey, product that's cheap, SMALL, and user friendly. Something that would work with a small antenna or PCB antenna would be good too. Any suggestions? Or any features I should be considering and have not listed here?

A friend suggested ZigBee but that can be costly.

Basically I have no idea where to begin designing this RF link and would love any bits of info you have to share.
