Mathematical model of quasi-harmonic generator of mm-range for biomedical application

Abstract

There is a stable trend of output power decreasing for mm-range generating apparatus of biomedical application. The quasi-harmonic generator is substantially complemented by the designed devices. It consists of the IMPATT noise generator and tuned narrowband filter. The output power of generator can be roughly estimated by means of the known methods of equivalent circuits. But that doesn't take into consideration the external loading effect. In the article this problem is solved through numerical methods. The mathematical model is used to design the narrowband noise generator with low power level for the study of mm-range radiation of bio objects. The results of researches are presented.
