Provides transfer function that is essentially logarithmic, with slop of 5 to 7 db per octave, to serve as bias volage for differentical combiner of i-f amplifier in troposcatter f-m receiver. Amplifier control range extends 40 db above threshold. Signal-noise ratio of highest baseband channel is 70 db.-P. Gruber, Crystal Converter for Tropo-Scatter Receivers, Electronics, 31:15, p 78-82.
