The main advantages of the (30-512 MHz) bands are the long communication range, especially used outside the city. Radio stations of such bands work perfectly both in low-terrain areas and in multi-storey buildings. In radio stations, broadband matching devices (Broadband control systems) are used to ensure the transmission of the maximum signal power from the source to the load. They are usually optimal for complex loads with fixed parameter values. It should be noted that the load impedance, to varying degrees, varies over time. For this reason, the BCS is usually not strictly optimal. The parameters of the matched radio engineering system (Radio engineering communications) with the BCS differ slightly from the optimal values. This suggests that the BCS used are quasi-optimal. The article proposes a method for the synthesis of broadband matching devices that adapt radio engineering systems to the changing load impedance.DOI
