I looked at this Attenuator:
And there are some specification I don't understand. So what is Resistive Element? I wonder if it is always "Carbon on laminated paper"!!? If so, why they put it in there? Same question to Wiper Contact.. isn't it always "Metal"??
Thanks.
A very good desciption of what it is.
No.
See above.
No.

Do you think the differences in material would matter a lot?
Element could also be conductive plastic, or cermet. I think they are implying paper phenolic board by "laminated paper". The contact could be graphite, as it sometimes is on wire wound pots.
It looks like 3 sides of the rectangular box are linear motion variable resistors, connected together to form a constant impedance, T attenuator.
Probably not for this application, where the setting is not likely to need adjustment on a daily basis.
It certainly can. Depends a lot on the application.

Its rated to 900 MHz. Its basically a standard constant impedance 75 Ohm video level control. I've seen lots of the older through hole version in Sat receivers and video processing equipment in the broadcast and CATV industries.
