low cost wireless transceivers with tunable frequency and power

[mr_anderson]

Hi
I am looking for a low-cost wireless module that is working on the 2.4 Ghz or 5 Ghz (or any other unlicensed frequency). I will be using it to run in-lab experiments. My preference is something with variable output power and tunable frequency. Most importantly I want the module to function as a typical transmitter i.e., it doesn't come loaded with any protocol or stuff like that because I want to control it with my own controller.

Any recommendations, ideas would be highly appreciated. I did some search on the internet and got some candidates like the ones from the cc family by Texas instruments but getting more feedback from you guys will be more helpful.

Regards.
Anderson.

I have been using some of the Hope modules at 868MHz and 915MHz and am pleased with them. They use the Semtech chips I believe. They also make 2.4GHz modules but I haven't used them.

Go with nRF24L01+ module. you can check this site for more info and it is cheap.operate in 2.4GHz.

I believe the nRF24L01+ is a chip, not a module.

Hi
mailus, I understand that the nRFL01 has some predetermined 125 channels so I can choose a channel not a real specific frequency, is that so?

Keith, thank you for your note, a chip or module will do it for me. Thx for pointing that out.
