Exact item shown, Isolator, works well, 5.75-8.25 GHz, one internet site says "Isolator  10-12 GHz. min. 25 dB isolation 1.01 db insertion loss SMA (m,f)"  however  you can see clearly from the analyzer plots that it is absoutely not that.  From the plots, this is good from 5.75 or 5.8 GHz to 8.2 or 8.25 GHz, it's pretty clear - please look at the two analyzer plots - same test setup, I just moved the markers in the second plot to round numbers.  Note that there are two different configurations, the -008 shown in the first photo, male at the bottom, female on the left, and option -103 which is shown for the second unit, male on the left, female on the bottom.  I don't think it matters, but if you care, just say which one you want and I'll send you that one if I still have it.

note to me: computer hutch, right side, yellow bin #1, not in a plastic bag
