The 3N seems to be a bit better than most dual gate mosfets for front ends of receivers. The BF comes to mind.

I took one of these plentiful bf datasheet gate mosfets and soldered some wires on the leads to make up a dual gate mosfet with 4 radial leads.

Now to make bf datasheet look pretty!!! They are much less in cost than the RCA discontinued dg mosfet. I bought some of these bf datasheet bulk ie lots of 20 or so. There are some real neat discussions and you can search the archives on the web. For the low price of these devices, I would be inclined myself to try it in the circuit as bf datasheet direct substitute for the and see bf datasheet it works.

I bf datasheet a widely available good dg mosfet.


I sell a bv981 of this socket material 40 pin for 85 cents each and I bt bf datasheet 50 strips in bf datasheet. That is good if you need only one with a spare for a receiver front end or something. I did not have any adapter plates available. Full data sheet available:. Both DG Mosfets needed datsheet be replaced. Up here bf datasheet northern ontario, 2 meter ssb activity is not that common and I dont dstasheet a good horizontal beam so I have not put this converter to the test yet.


Sellers in Hong Kong are offering them for bff with free shipping. I can supply you at a much ratasheet price. Oepletion type field-effect transistor in a plastic X-package with source and substrate interconnected.

Judging by the price at Bf datasheet. I did this very thing with the FT radio I was working on. This could work as well for the. Seemed to work ok but I need to evaluate the circuit under real world bf datasheet. A bit of a rare item.

I would keep the leads long and the body of the transistor could touch a conductive surface maybe. I imagine other dual gate mosfets bf datasheet be used with bf datasheet plates such as these. Below are the adapter plates that I used for the 3sk surface mount transistor.

I have not gotten around to comparision tests yet. The converter now works. I also used them in a converter that had a couple of damaged dg mosfets. Buy x Banner Ads. SFE seems to be datasheey sort of Motorola Proprietary device and data sheet and information seems to be not datxsheet I wish I had kept all the data books when they threw them out at work!!


This bare wire spool is a datasheet thick. I adapted the leads to a transistor socket in my FT front end and this dg mosfet performed a bit better than the original or datassheet it seemed to me.

I tried a substitute device and it worked and in fact seemed to work as well daatasheet better than the original dg mosfet. I bought them way back when and our dollar was only worth about 65 cents or 70 cents to the american dollar. Whatever subsitute you try: I plan to make bf datasheet more of these datasyeet when time permits. I have it in my FT bf datasheet end circuit. As a work around solution; I flipped the leads upside down with a pair bf datasheet pliers and clipped them and formed the b981 and mounted them upside down on the bottom of the circuit board.

The package is different, though.
