Sources for additional attenuators

Postby w-u-2-o » Thu Jul 13, 2017 1:23 pm

You can buy a very nice kit from Mini Circuits, in either BNC or SMA form factor, that comes with a selection attenuators that can be put together in different combinations:

This is an example of one of the BNC kits:

However, an even better solution would be a fixed 10dB attenuator combined with a 1 to 10dB rotary step attenuator. They are always lots of relatively inexpensive rotary attenuators on eBay:

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xrotary+step+attenuator.TRS0&_nkw=rotary+step+attenuator&_sacat=0

That way you can dial in to a dB exactly how much additional external attenuation you want/need.
