How precise does your level have to be? How stable?
There are surplus attenuators available all over the place, some variable
MiniCircuits has VAT-nn attenuators which are relatively inexpensive (not by
"found it at a ham-fest 30 years ago" standards, though)
Building your own attenuator using chip resistors is another possibility.
