Abstract
A six-stage successive detection logarithmic amplifier is described in which each stage is a GaAs monolithic microwave integrated circuit (MMIC) incorporating RF amplification, detection, and a novel video summation technique, using standard 0.5- mu m process field effect transistors (FETs) and Schottky diodes. The circuit had a dynamic range of 80 dB at 3.8 GHz with linearity of +or-1 dB and power dissipation of 4.0 W. RF and video processing have been incorporated on a single die. Pulse performance and other parameters are summarized.<>
