I agree but the datasheet says it can drive significant power in the
1MHz to 2MHz range...-- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico@nctdevpuntnl (punt=.) --------------------------------------------------------------
No, I just refined it with another (obvious) term or two. I don't remember what they were now. Google is funny, if you give it too many terms it seems to sometimes not find things that contain all the terms.
$9 each in small quantities, in stock.

Some of them try to get Phyllis to learn something. ...or even read.
Thanks for the very specific information ... but surely there has to be a more straightforward way to get 50 Ohm impedance. I would rather not use surface mount inductors or complex in-house fabrication to replicate them.
Why is it assumed the 50 Ohm impedance necessary anyway?
How about a 1:1 coupling transformer in a pot core, with the cap (shown in your schematic). What are the drawbacks with that?
Many years ago, for a similar application I used an Elantec EL2030 to provide some gain, with an EL2009C buffer (90MHz, 1Amp). Sadly I think these may now be hard to get, as like all unusually good chips they got discontinued.

The EL2030 was a crude beast, though--lowish transconductance and really high distortion iirc. I still have some of both in my drawer.
