[Hackrf-dev] HackRF-dev Digest, Vol 21, Issue 4

[Dimitris Siafarikas]

Hi,

At the lab I am currently doing my thesis on SDR, I have various test
equipment for wide range of frequencies including a VNA ranging  from 25 Mhz
to 50 Ghz. But I do not have a HackRF. Is there any way of someone lending
me one?

I do have the calibrated test equipment, though I'm not sure above 2 or 4
GHz.


But the performance (i.e. gain, noise figure, and image response) vs
frequency 10-6000 MHz is not what I was asking. That was the IF response,
i.e. for antialiasing knowledge. Does that vary with the RF frquency?  That
information is VERY useful to everybody.

That is a difficult question to answer in a way that is useful to people who
don't have calibrated RF test equipment.  And even for those who do have RF
test equipment, I do not yet have enough data over very many frequencies
over many units to perform statistical analysis.  If this is a project
anyone wants to work on, please let me know.
