description: The work is devoted to the development and research of amplifier circuits for processing antenna signals in Multisim program, as an object of research was used chip "logarithmic amplifier". Here we present the development of a logarithmic amplifier consisting of four main components: a preamplifier, a detector, a logarithmic amplifier based on AD8132 + AD8310 and a compatible amplifier. The chip under study and development allows to process with high accuracy the microwave signal received from the antenna, due to the characteristics of each of its elements. In the course of the work, test measurements of the characteristics of the "amplifying" elements of the studied and developed microcircuits were made, and at the stage of research the characteristics of the detector part and the components of the logarithmic amplifier of our object of study were simulated. As a result, the characteristics of the logarithmic amplifier were assembled and experimentally investigated, and its gain was simulated in Multisim, which allowed us to understand exactly that our requirements are met. When building a radio-frequency path the problem of signal processing with a large dynamic range arises. Therefore it is important to implement a node that processes both strong and weak signals. The result of this work solves the signal processing problems of the antenna due to the large dynamic range, which allows it to have high sensitivity to both weak and strong signals. The assignment for the graduate qualification work has been completed in full.
