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

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

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.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
