Look for AMP 3284-3201-10 on eBay, it is available from various sellers. It's an obsolete part, I don't see it anywhere else.
Swainster:
Yep, that's it - should have guessed that it would be SMC on the inner end. I'd never seen an SMC in the wild until I took apart an HP RF sig gen.
RichardM:
I would be interested in trying to build this for my 5334a :)
Were the gerbers uploaded somewhere ? The small sized components may be a challenge for my hobyists skills.

Hi Richard,
I haven't uploaded the Gerber's yet. My plan was to make a V2 with some upgrades, like an inline LNA. In reality though I've actually been pretty happy with the design as is. Maybe one day, but for now it meets my needs.
I will make the one or two revisions that were bodged in and upload the files by the end of the week. Glad to see this project is helpful to the community!
As for soldering the small parts, a solderpaste stencil and some tweezers made quick work of it. If you aren't comfortable with 0402 though, there are assembly services out there. I was able to do it with a hotplate and patience. To be honest my soldering experience exceeds my design experience for this sort of thing, so I may be biased in encouraging you to go for it.
RichardM:
Thanks very much. No hurry.
I guess I could upsize some components by editing the Gerber for my needs and stock avaiability ? Is it single sided ?
Cheers
Richard
