The adapter plate is a much superior method. You can mount them upside down on a circuit board bf981 datasheet solder them in. I bought it at Radio Shack some time ago. They are much less in cost than the RCA datwsheet dg mosfet.

Judging by the price at Talon. I did not have any adapter plates available. Iam a technician not engineer. Im sure if you are careful a 25 watt iron would do even if it is not grounded tip. Another substitute is the 3N I dont have a whole bunch I can spare however. That is good if you need bf981 datasheet one with a spare for a receiver front end or something.

I do have about a dozen or so that I have carefully bought over the past few years from hobbyists and from ebay datqsheet ect. The dual gate mosfets are some in house part number bf981 datasheet by some company but are supposedly similar to type 3n dg mosfets. The good news is that dataasheet are all less than a buck at Digikey.


Where I used to work for 18 years with Military and ex Military Technicians and supply people I was sternly told dataheet t “work around bf981 datasheet were not the way to do things.

These are old stock items from a collection of a ham radio mans junkbox. Not sure if it is low noise and good sensitivity or not. I have bf981 datasheet 40 or 50 currently in stock. Bf981 datasheet adapted the bf981 datasheet to a transistor socket in my FT front end and this dg mosfet performed a bit better than the original or so it seemed bf981 datasheet me. I took one of these plentiful dual gate mosfets datashee soldered some wires on the leads to make up a dual gate mosfet datasbeet 4 radial leads.

I also used them in a converter bf981 datasheet had a couple of damaged dg mosfets. I datassheet I had kept all the data books when they threw them out at work!! The pin out is a similar layout to the metal can package dg mosfets and with a bit of lead forming they can be used bff981 place of the radial lead transistors. I did this with my FT on the RF board and the circuit worked as well or better with this substitute. I hope this is a help. The package is different, though.

I did datashete very thing with the FT radio I was working on. As a work around solution; I flipped the leads upside down with a pair of pliers and clipped them and formed the leads and mounted them upside down on the bottom of the circuit board.


I will try and buy some more stock but in the mean time. This is an bf981 datasheet meter receive converter than ouputs on 27 mhz!

Both stages are dual gate mosfets. Commercial vendors bf981 datasheet manufacturers would not do this unless they could not avoid it. Ive done this too as a “fix” JUNE 12 updated with new information and pictures. Navigation Link to www. I have about 40 bf981 datasheet so available.

These “house numbered” dual gate mosfets were bought by me back in around the year or so from a fellow on QRP-L the bf981 datasheet and qrp list I belong to. I have not gotten around to comparision tests yet.

datsheet Another thing I do with bf981 datasheet gate mosfets from time to time bf981 datasheet I test them in the receiver front end circuit of my FT I dwtasheet send in an envelope. I think they are similar to 3n I can bf981 datasheet it up. They seem to have some good stuff at good prices.

I’ll take some pictures when I try this myself in the near future. I used one by forming the leads and it worked quite well in my FT replacing a dual gate mosfet in the rcvr front end.
