А resonant amplifier with a tuning frequency of 64 MHz is Considered. The diagram and photo diagram are shown. The results of the experiment are given in the form of a technique, amplitude-frequency characteristics in a wide and narrow band, and amplitude characteristics at a frequency of 64 MHz. It is shown that the maximum gain is 14 dB in the small signal mode.
The development of protection complexes from air attacks using unmanned short and ultrashort range aerial vehicles (UAV) is one of the most relevant application areas of modern robotic UAV. In connection with the requirements strengthening for mass-dimensional characteristics in the construction of an on-board control system (OCS) for an UAV, the main task becomes preserving and improving the accuracy characteristics of an OCS. Solving integrated processing of information, interaction in-group, intellectual guidance problems it is necessary to use high-speed digital microprocessor for signal processing like a part of an OCS.
