description: This work is devoted to the study of an ultrawideband signal receiver based on a logarithmic detector. The methodology of this study combines an empirical (experimental study of the reception of ultra-wideband pulses by a receiver based on a logarithmic amplifier) and theoretical (work with technical sheets of microchips, their further comparison and analysis) types.
In the course of the work, the device of the logarithmic detector was investigated and a comparative analysis of the AD8317, AD8318 and AD8319 micro-circuits containing this detector was carried out. It was obtained from it that the AD8318 microcircuit will be our most universal choice.
We also investigated the operation of the detector with pulsed signals (short duration) in two scenarios: using additional filtering in the circuit; using only the logarithmic amplifier. For further work with the presented circuit, the experimental amplitude-frequency characteristic was taken as a reference material in order to more accurately evaluate its behavior in further applications. The char-acteristic is studied in the range from 1 GHz to 3 GHz.
The scope of the studied receiver can be identified as narrowband wireless data transmission systems. This scheme provides a compact and functional in-stallation.
