The research object is the process of converting the signal proportional to the pressure, humidity, gas concentration and temperature into a frequency signal, which allows to solve the problem of development of radio sensors of physical quantities with improved metrological performance. The research subject is the static and dynamic characteristics of radio frequency sensors of physical quantities on the basis of reactive properties and negative resistance semiconductor structures. The paper in the scientific aspect of mathematical models of radio sensors, pressure, humidity, gas concentration and temperature based on nonlinear equivalent circuits that allowed us to obtain a conversion function and sensitivity equation proposed devices.Developed physical and mathematical models to describe static and dynamic characteristics of microelectronic sensors, pressure, humidity, gas concentration and temperature. The analysis of the physical processes that occur in bipolar and field effect transistor structures with negative resistance under pressure, humidity, gas concentration and temperature. A design element theory tenzo-, moisture- and gasreactive effects in the field and bipolar semiconductor structures underlying mathematical models proposed frequency sensors. A modeling study tenzo-, moisture and gasreactive effects in the field, bipolar and bipolar field effect transistor structures with negative resistance using the software package Matlab 7.11 using PSpice models of bipolar and field-effect transistors. The results of model studies have high convergence of results obtained using the developed mathematical models of radio sensors, pressure, humidity, gas concentration and temperature.
