Eventually.... I will use this converter module in a circuit I am developing. I am building an HF
receiver from parts that I have gathered. I have the main board mostly finished. It will receive in the
1.8 to 30 mhz range. This converter will allow me to receive 2 meter signals with that receiver.
I will post some pictures of the project at a later date..cheers..and 73 Earl VE3AB

What we have here is the
underside of the circuit board and
a group of spare dual gate mosfets.
The dual gate mosfets are some in
house part number used by some
company but are (supposedly)
similar to type 3n201 dg mosfets.
When mounted on the top
(component side) of the circuit
board; the pin layout does match
the pattern layout but the pins
themselves are too thick to go
through the holes in the circuit
board.
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.
This is "OK" for amateur use.
Commercial vendors and
manufacturers would not do this
unless they could not avoid it.

The converter now works. I dont know if it is working real well or not. I'll have to wait for
a vhf contest and switch back and forth between the converter and my 2 meter
multimode to see if the sensitivity is good or not.

I may be adding some more to this page at a later date ..when and if I decide to use this converter in a practical circuit or two.
