If you don't have this in your edition, let me know and I will scan the relevant paragraph and the diagram. They say the circuit will operate to 100MHz or more and it solves the problem of detector non-linearity.
I mentioned this circuit before on a thread about how to make a low level RF milli-volt meter.
