Looking for information on building a simple Spectrum Analyzer
(OP)
I am looking for to build a simple spectrum analyzer. I need to measure frequencies from 2GHz to 6GHz, or at least from 5GHz to 6GHz. I found a few designs that use UHF and VHF tuners, but they do not measure the frequencies I need. I will be using it for site surveys for WLAN applications in 2.4GHz, 5.3GHz, and 5.8GHz. This is my first RF project. Most of my experience is with the Biomedical and computer/netwroking fields.
Thanks
Thanks

I'm thinking of the scope plugins that cover 10MHz to 20GHz in an HP140 scope.
They are more difficult to use than the latest computer controlled wizardry, but still do the job (once you've figured out how they work!).

You might have a look in the Arrl Microwave books for mixers and oscillators that will work at that sort of frequency.
Bear in mind that electronics begins to resemble plumbing above about 2GHz.
I suspect that if this a work type project, after you've played with the home brew stuff, the 2nd hand HP141T and spectrum analyzer plugin are your best bet.
If it's for your own hobby interest, then have fun!

use a preamp/mixer the osc. frequency switched with the PC.
