Abstract
A logarithmic amplifier which uses the distributed amplifier as the basic underlying element is described. The successive detection technique is used and leads to a logarithmic amplifier with a 65-dB dynamic range operating over the band 2 to 6 GHz, with a deviation from linearity in the middle of the band of +or-1.0 dB over the dynamic range. Over the specified band, a further deviation of +or-1.3 dB occurs. The effect of varying temperature from 0 degrees C to to 50 degrees C increases this figure to +or-1.7 dB. The rise and fall times (including the associative video amplifier) are 7 ns and 20 ns respectively.<>
