Electronic Goldmine has some Pulse Engineering LAN transformers (same as
those used on many LAN boards) on clearance at $1.00 each.

Datasheet is at http://www.datasheet4u.com/download_new.php?id=541958
Quite cheap, in my opinion.

List,
I have seen on the net a 10 MHz filter using 10.7 IFtransformers but
have no idea how well they would work for isolation with thenew style
Lucent boxes.
Thoughts?
On Ebay venders are offering 10 MHz crystals for almostnothing if you
buy 30. My question wouldthese be good for making some type of simple
ladder filter?
In his article *Modifying Lucent RFG-M-RB Rubidium FrequencyStandard*
the author used a 10MHz filter that was taken from an old
10MbitEthernet LAN board. The part number he used was 20F001N and I
found them onEbay for low prices.
Now I don’t have any access to any old ethernet LAN boardsso I’d have
to build from scratch.
Does anyone of these methods have an advantage over theothers on the
new style Lucent boxes or in the making of a small
distributionamplifier with good isolation?
Regards,
Perrier
