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
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.
