That and the were used to supposedly daasheet the front end performance gain? Jan Wed 09, 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. I think you mean 3N? Jan Tue 08, 1: Jan Xatasheet 10, 2: Dan’s Small Parts has them in stock.
Jul Sat 05, 3: A dual-gate FET has 4 connections, therefore is a “3N” number. He apparently let the domain registration expire. Remember, as supplies dwindle, opportunist sellers raise prices.
You might find some Japanese parts I have RCA if you still need some. RCA dual mosfet. Maybe I’m just trippin’. Japanese continued to make 3SK-types for many datassheet years. I was with Siliconix in the 80s and 90s.
We discontinued dual-gate in the mids. Name is for sale. Previous topic Next topic. Try Dans Small Parts ” www. I would go with the 3N, maybe. Mixer or RF Amp.
I wondered how this could be and came up with the following conclusion. 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. He’s been selling out stock on eBay Jan Wed 09, 5: Dec Mon 31, 3: Barry H Bennett, frankradio1, Google [Bot] and 2 guests. If it’s for a repair, you might solder one tiny! 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.
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. I could fine no currently produced dual gate RF fet and could fine only a small number of current production surface mount devices.
Books Support This Site: Jan Wed 09, 4: Mouser and Avnet have these.

But it may also depend on the freq. Someone must still make one! Isn’t the 2N an equivalent? Look at what is being produced in current electronics products and what percentage of stuff still dafasheet is not surface mount? For this reason these useful parts no longer have a significant OEM market and have been widely discontinued.
Actually non SMD components are not a bad thing to hoard away overall. RCA dual mosfet Posted: Is there a direct replacement for the out there somewhere? Jan Sat 12, 7: I came up basically empty-handed.
Getting harder to find, cheap.
Some 3n210 picked up the home page and that’s all. Something about that number rings a bell. Still used in aeronautical radios. Got a in my junkbox, but I’m keeping it to repair a HW-7 I have. Jan Tue 08, Page 1 of 1.
There’s a few on eBay which are waaaaaay too expensive. Jan Tue 08, 2:
