John Dyson wrote in message ... 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!!!) John |
