Hi, everyone. I have a question about buying small amounts of
RF varactors with a few pF ranges.
Actually I found that
many manufacture websites such as Areoflex, MDT, infoneon, etc.
Should I directly contact the manufactors or the sales distributors?
Do they like to provide small amounts of the varactor to students?
I am really not quite familiar with the buying procedure, and
will appreciate any information about it.

Getting RF parts in small quantities can be tough.
There is no doubt. Generally, the suppliers want to sell to cellular
phone companies, not students or small OEMs.
you can get them through distribution. Stick with Digikey and Mouser
as they will sell small quantities. The big disties like Future
will not usually break a reel for you, and yo don't want 3000.
Digikey sells Toshiba varactors (page 1090 of their latest catalog).
Mouser sells Zetex varactors (page 379). The Zetex diodes are hyperabrupt,
so they are good where large tunign ranges are needed.
other option is to try and get the manufacturer to sample some parts
to you. This is a hit or miss proposition. If it were me, I would
try to find a way to make the Toshiba or Zetex parts work and order
them from one of the catalog companies.
