Wilkinson Power Divider for High Power Amplifier Employed for Wireless Communications
No full textHigh power amplifier based on the Wilkinson energy has been constructed and fabricated in this study. The 45-50W primary speaker unit is manufactured using horizontally distributed metal oxide semiconductor (LDMOS) materials and ferromagnetic materials. Field Effect Transistor (FET) Transistor PTFA260451E. Wilkinson Energy Complex has employed to merge dual entered energies to achieve 90 watts of power. The suggested power amplifier was investigated, planned and advanced utilizig (MATLAB) software traditional Wilkinson power dividers (WPDs) might produce acceptable response near to suggested center frequency Anyhow, such WPDs might further displayed low out of range response whereas it needs adding significant procedures. In favor of enhancing the preset performance state, a modification has been made Proposed utilizig microstrip WPD which shows significantly improved stopping range with large separation. A low-pass filter (LPF) model is employed in each sections of the harmonic damping splitter to save power. The suggested structure is constructed using microelectromechanical system oscillators (MEMS) against the film's sonic resonator (FBAR) with a center frequency of 2.65-3 GHz with two sections and 50 Ohm impedance for 90 watts amplification power

Algorithms for the Selection of Relevance Functions of the Intelligent Measurement System
No full textAlgorithms for initializing the values of relevance functions of the intelligent measurement system and its component software package are considered in this paper. On the basis of the proposed algorithms, a classical multilayer network with correct connections was developed to solve the problem of signal filtering
The Effect of Planting Period And Strategy on Sunflower Variety Yield
No full textthe article cited data on the yield of sunflower varieties ertapishar SAMQKHI 20-80 and SUR varieties when planted as a recurring crop on land vacated by Bush grain crops in different (July 1; July 10; July 20) terms and in 70x20x1; 70x25x1; 70x30x1; 70x40x1 CM planting schemes. As the planting period was delayed from July 1 to July 10 and from July 10 to July 20, there was a decrease in yield depending on the variety. In all the planting schemes studied, from 70x20x1 CM to 70x40x1 CM of nutrition there was a good growing development of plants due to the expansion of the area, but due to the low number of bushes at the expense of the area, a very high yield was not obtained on the account of hectares. As planting dates were delayed, the flowering phase of the plants corresponded to the 2 decade of September. At these times, due to the reduction of light days compared to sowing in the period of July 1, the pollination process did not pass in moderation due to the observation of wind, dust dust and precipitation, and at the expense of hectares, the yield decreased by 10-12% for the period of July 1 and 15-17% for the period of July 20. The highest yield in general was obtained in the samqxi 20-80 variety in a 70x30-1 cm planting scheme for the period of July 1 to 33.8 s/Ha. Also for the period of July 1 by the Sur Variety, the highest yield was achieved in the 70x25-1 cm planting scheme with an indicator of 29.5 s/Ha

Значение Самостоятельного Образования Будущих Учителей Технических Наук В Процессе Формирования У Них Специальных Компетенций
No full textОсновную долю развития университетского образования на мировом уровне составляет самостоятельная работа студентов, а основная направленность отчетливо прослеживается в тенденции перехода от преподавания к обучению. В связи с этим с переходом на компетентностный подход в образовании, формированием системы навыков и квалификаций для самостоятельной работы, необходимостью воспитания у обучающихся культуры самостоятельной работы, низкой долей самостоятельных учебных часов в система высшего образования, самостоятельное обучение студентов, Разработаны предложения и рекомендации по внедрению методов и технологий, направленных на усиление критического и творческого мышления, системного анализа, отсутствия предпринимательских способностей, организаторских способностей студентов в образовательном процессе, внедрению технологий , были представлены выводы
Технологии Термоциклической Обработки Для Повышения Износостойкости
No full textПредприятия сельскохозяйственного машиностроения Республики Узбекистан постоянно увеличивают выпуск хлопкоуборочных машин. При эксплуатации данной техники в результате абразивного изнашивания выходит из строя таких деталей как зубчатые колеса и вал-шестерени, в результате чего ежегодно расходуется большое количество металла для изготовления запасных частей. С каждым годом машиностроительная техника становится более сложной, и для обеспечения ее эффективного использования необходима мощная ремонтная база
