At one time, Microsemi would "sample" them out to hams, in addition to their 
usual commercial and military customer base.  That was back in the early 
'90s.  Quite a few folks took advantage of it and my understanding is they 
will no longer sample-out to the ham community.  If you do request a sample 
through their website, expect to answer a lot of tough questions by 
telephone from their sales force.  It's understandable as these are 
expensive diodes -- something like $40 each in small quantities, maybe more. 
These are 1KW PIN diodes that are meant to switch RF, specifically at HF 
frequencies.

You can try the usual on-line sources for quality industrial components like 
Newark, Allied, Digi-Key and Mouser.  If that fails, you'll need to contact 
Microsemi and make an inquiry about obtaining the name of an industrial 
supply distributor near you.
