I have one up converter from DMC in the 2 GHz range -- PN 131-110751. I played with it on the bench a bit. This one takes +12 V input as opposed to most other DMC stuff which used 8.4 V. The output produces about 2W and, as I recall, it works fine in the ham bands. I intended to use this to build a ham radio for 2 GHz, but have never gotten around to it.
