Check the listing for details. Kratos/General Microwave Programmable RF Attenuator 2.6-5.2 GHz 60dB 3453H-605. Condition: Used. Listed at 35.00 USD. General Microwave/Kratos Pin Diode step attenuator, 3453H-605, 2.6-5.2 GHz max atten 60 dB, min step .03 dB. The "H" in the part number stands for "High Speed" my analyzer covers only up to 3 GHz, I tested this unit (see plots) but I couldn't test it over all of relevant frequency range, what I could confirm is that I could see some change in amplitude for each but the smallest step sizes. The tech data for these is on line at the Kratos site, here: https://www.kratosmed.com/-/media/gm-catalog/b/g25_1.pdf, on page 41, 44; I have put copies of those pages as the last 4 pictures in this listing.. Note to me: top gray drawerI normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box. Check out my other items!
