"Phil Allison"
Function generator. Integrate square wave to get triangle wave. Shape
triangle wave to sine wave using a couple of diodes. See
http://kitsrus.com/projects/k23.pdf
** Contrary to the OP's wishes, that POS uses op-amps.
Have you seen the ugly " sine" wave it produces ??
The diodes will rectify the RF energy.
Not even a starter.
Contrary to what you think, the OP seems like he would be happy with a
sine wave with only 1% distortion.
** Fraid that POS has a lot more than 1% THD.
The diodes will rectify RF but at
the output the signal level should be several orders of magnitude
higher than the RF.
** The OP wants to link his device to a transmitter.
The amount of RF energy is serious.
Did you read his post at all ??
So would not expect that to be a problem.
** Yawnnnnnnnnnnnnnnnnn....
