Yüksek Verimli F-Sınıfı Mikrodalga Güç Yükselteç Tasarımı
Özet
Modern radar and communications applications, the transmitter output power is the decisive factor in the design of the system. As a result of this, the design of power amplifiers that can provide a high power output has gained importance, but in this case, the consumed power has created more problems. Great cooling system that uses manufactured devices to solve this problem. This solution increases the system cost increases. Turn to the system of today's technology small and portable, and wanted to reduce costs by reducing energy consumption, new solutions are required. In this case as the solution by lowering the level of power that is consumed in the power amplifier, aimed to increase the efficiency of the power amplifier. Switched mode power amplifier designs (the Class E or Class F), high efficiency offers. Class-F power amplifier design are designed to be appropriate to have even and odd harmonics in the impedance value. Current and voltage waveforms, with the control of each harmonic is reduced to overlap and as a result, the power consumption of the power amplifier is reduced. In this thesis study, Class-F power amplifier with 72.2% drain efficiency, which provides an output power of 41.93 dBm at 2.6 GHz frequency has been designed.
