Abstract
A logarithmic amplifier with a large range of input signal magnitude at high frequency. The amplifier comprises a number of similar stages arranged in cascades. Each stage has a logarithmic converter and an input stage constructed to maintain a consistent phase of signal and to feed a different range of signal amplitude to the respective converters. The outputs are summed.
