I recently had to look for something similar. A current part might
be the NEC (CEL) NE46134... It is probably a little faster than parts
like the 2N3866, and also is lower voltage, but for a new design might
be somewhat useful (and current.)


Thanks. Is there a current "List of desirable RF transistors for
2003" floating around? If not, would anybody else like to contribute
some part numbers here?

I dont' have any 'lists' per-se, but you might want to look at
www.cel.com (for the US rep and info for NEC transistors.) philips
and siemens (infineon.com) also have a current line of RF components.
For slightly higher frequencies, the agilent phemts are actually
really practical for as low as 50MHz (but probably 200MHz in reality.)
For RF gain modules, the sirenza (sp) parts are really good (and
in some cases, the original OEM for the Minicircuits gain parts.)
(Their SiGe parts are usually reasonably priced, have low NF as low
as 1.9dB, and SiGe parts tend to have good low frequency NF also.)

The manufacturers that I listed above tend to have fairly good
spec sheets and have SOME US availability. Often, there
is the terrible issue of QTY3000 type order requirements, but
that isn't always a problem.

For distributors, you can try mouser.com, newark.com, avnet.com?, etc.

Mouser has a fairly good stock, and so does newark... Sometimes, the
distributors have 'good deals' on designers kits. The designers kits
usually have anywhere from QTY3 per part number on up to QTY10 or higher.

I usually play the game of looking at the suppliers spec sheets, and
the distributor's availability lists, and then compare the two.

(I know that this isn't directly answering your need/questions, but can
get you started if no other info is provided to you!!!)
