Contrary to what you think, the OP seems like he would be happy with a
sine wave with only 1% distortion. The diodes will rectify RF but at
the output the signal level should be several orders of magnitude
higher than the RF. So would not expect that to be a problem. The
reference to the kitsrus was to show one implementation that had an
explanation of the circuit.
