| description | Today’s practice of developing VHF radio systems paths widely uses MMIC as low-noise amplifiers. This approach is acceptable for radio systems operating in a relatively quiet electromagnetic environment. However, for systems operating in a complex interference environment of the VHF band, low-noise amplifiers with a lower gain and increased overload capacity are desirable. This requires maintaining a low noise figure and manufacturability of the device. Therefore, the solution to this problem requires the development of a low-noise amplifier of the VHF band with increased overload capacity, made on commercially available MMIC. This paper presents the results of a logical-heuristic synthesis of a VHF low-noise high-linear amplifier performed on an MMIC, utilising noiseless negative feedback technique. Analytical expressions are given for calculating the gain, the input gain compression point, input intercept points of the J-th order, and the noise figure of the structure. The analysis of the performance of the amplifier implemented on the MGA 62563 MMIC showed that, in comparison with other integrated solutions, increased overload capacity and structure linearity are provided. The high noise immunity and ease of manufacture of the device using commercially available components, make it a promising element in the design and modernization of VHF receiving and amplifying paths operating in a complex electromagnetic environment. |
