A PRECISION, WIDEBAND LOG-VIDEO AMPLIFIER OF LARGE DYNAMIC RANGE.

Abstract

This report describes a video-logarithmic amplifier which has the following overall characteristics: an accuracy of better than + or - 1 db when compared to a true logarithmic response; the capability to match to an HP-423A detector so that the combination of detector and logarithmic amplifier will produce an output which is the logarithm of the input rf pulse; a dynamic range of at least 90 db when operated from a 50-ohm source; a rise time of less than 0.1 musec. In addition, it is completely solid state with 13 transistors, 3 high-speed diodes, and 7 Zener regulator diodes. The basic design technique, circuit details, measurement data, and alignment procedure are presented. (Author)
