How to buy the RF varactors with small amount for prototypin - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.

Usually, though, 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.

The 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.
