2.4GHz designs/test equipment

Post by Rodney » Sun Oct 14, 2012 12:14 pm

Is there any recommended sources for literature to help in the design or building of test equipment for use in the 2.4GHz frequency range? Sources for components for this frequency range?

What specifics are you testing?
Thanks for reading Design Cycle and HAVE FUN,

Trying to look at the wave forms put out by the different RC radio controlled transmitters, i.e. Futaba, Hitec, Airtronics, FrSky etc. ) to see the modulation pattern. I have a breadboarded unit that works after a fashion but it is not very sensitive, I have to be within 5 to 10 inches from the pick up antenna to get a decent signal. I suspect that I need a better diode in the detector circuit. I can not seem to attach one of the images I get off my oscilloscope to this note or I would. I tried clicking the Img tag above but there is no instructions as to how to bring up the image from the file it resides in.

RC radios are in the 27MHz, 50MHz, 72MHz and 75MHz bands.
I suggest getting your hands on the latest ARRL Handbook for design ideas.

Have fun,
Fred

I'm afraid you are a little out of date. 90% of all RC equipment is now using the 2.4GHz band. There is still a lot of the older frequencies you mentioned (I have and use several) but for the past two years 2.4GHz dominates the market. Up until about 10 years ago I was an active HAM and built most of my own equipment but the UHF area is new to me. since I have been out of the loop for the past few years, I was hoping for some info on the 2GHz area. Thanks anyway, Rodney

Yep.. I'm OLD..
Sorry for the oversight..
Obviously, I stopped following RC stuff a long time ago :shock:

I'm new to this site, browsing around, catching up on all the interesting stuff and come across this posting.

I realize this post is almost a year old, but I've recently been shown the Tunigy 9XR of which I hadn't previously known about.

I'm glad I paid less than half price for my Spektrum DX8 or I'd be crying more . . . :shock:

Open source 2.4GHz!
