Any update on the 6GHz version?
Hello blackbird,
It has taken me longer than I expected to get it done, but it is ready. I was actually supposed to release it 2 weeks ago, but due to delays introduced by the PCB house and DHL, I haven't. Right now I'm waiting for the customs proceedings on the final revision PCBs.
I expect to have them for sale starting with next week (I doubt DHL will delivery them today).
Cheers!
Edit: Btw, one of the reasons for the many delays is that I decided to market it as an 8 GHz option too, because I expect a bit better than -20 dBm sensitivity at 8 GHz (the working prototype on my bench does -25 dBm at that frequency). Anyway, don't rely on these numbers too much, since I might not specify it to these levels - I'll have to build several boards and extract a typical value first.
Edit 2: To put a bit of distance between my version and the Chinese one, I'll make a direct comparison between their specified sensitivity and the sensitivity I get on my current prototype (again, don't take them as final numbers, the final numbers may be worse):
| Frequency | Chinese (dBm) | Cojotech (dBm) |
| --------- | ------------- | -------------- |
| 100 MHz | | -14 |
| 200 MHz | -5 | -26 |
| 500 MHz | -12 | -34 |
| 1 GHz | -20 | -39 |
| 2 GHz | | -41 |
| 3 GHz | | -40 |
| 4 GHz | | -38 |
| 5 GHz | | -34 |
| 6 GHz | | -31 |
| 7 GHz | | -27 |
| 8 GHz | -20 | -25 |
