Jan Tue 08, Is there a direct replacement for the out there somewhere?
Someone must still make one! Jan Tue 08, 1: Try Dans Small Parts ” www.

He’s been selling out stock on eBay Jan Tue 08, 2: Click on the link at the top of the page. He is not going out of business, this is just his close out page. Jan Wed 09, Jan Wed 09, 4: Got a in my junkbox, but I’m keeping it to repair a HW-7 I have. There’s a few on eBay which are waaaaaay too expensive. If I find one or two for a reasonable price I’ll let you know. Something about that number rings a bell.
Maybe I’m just trippin’. Jan Wed 09, 6: Xatasheet and Avnet have these. If it’s for a repair, you might solder one tiny! Jan Wed 09, 5: Isn’t the 2N an equivalent? You might find some Japanese datasheef Jan Thu 10, 2: I would go with the 3N, maybe. That and the were used to supposedly upgrade the front end performance gain?
Getting harder to find, cheap. But it may also depend on the freq. Mixer or RF Amp.
Like, you don’t need the lowest noise for the mixer, I don’t think, but still get the characteristic improvements over a bipolar mixer. Jan Sat 12, 7: About two years ago I spent a lot of time trying to find a vender and part number for a dual gate MOSFET in current production- preferably leaded for a day job design requirement. I came up basically empty-handed.
I could fine no currently produced dual gate RF fet and could fine only a small number of current production surface mount devices. I wondered how this could be and came up with the following conclusion. For this reason these useful parts no dxtasheet have a significant OEM market and have been widely discontinued.
There is an opportunity for someone to come up with a small daughter board with a still available SM Dual gate fet that inserts nicely into the old fashion 4 lead type pcb footprint. The daughter board most likely would need some additional SM passive components to limit the UHF response of the SM fet in order to tame the UHF spurious osc that can be expected to be induced by the inductance of the leads.
Jun Datahseet 29, 4: Jul Thu 03, E-bay datashfet several choices. Jul Fri 04, Jul Sat 05, 3: I have hoarded what mosfets I could lay hands on easily. Still used in aeronautical radios. I also have hoarded some regular MPF type fets too as they are cheap at this point. Actually non SMD components are not a bad thing to hoard away overall.

Look at what is being produced in current electronics products and what percentage of stuff still made is not surface mount? Remember, as supplies dwindle, opportunist sellers raise prices. And if you can get a handful of useful parts now for cheap, they don’t take up too much room and saves grief later. Books Support This Site: Page 1 of 1.

He apparently let the domain registration expire. Some broker picked up the home page and that’s all. Name is for sale. I think you mean 3N?
A dual-gate FET has 4 connections, therefore is a “3N” number. Dan’s Small Parts has them in stock. I have RCA if you still need some. I was with Siliconix in the 80s and 90s.
We discontinued dual-gate in the mids. Japanese continued to make 3SK-types for many more years.
