Topic : Development of Radio Frequency amplifier system

  

 Scope  

                        The RF systems of the Siam photon source is supplied by the high-power RF amplifier. The present RF amplifier is based on the solid-stage device technology. Amplifier was procured from international company. There are several spare parts, RF boards and modules required to be spared at SLRI to maintain the reliability of this RF amplifier. To be able of design and fabricate this high-power RF amplifier will benefit the cost of maintenance and operation. Aiming of this project is to design and fabricate RF amplifier boards, then combining a low-power RF board into the high-power RF amplifier. This includes the design of RF components, such as RF splitter, RF combiner, RF circulator. RF testing and measurements will be also performed to ensure the efficiency and reliability of the whole RF amplifier. Control system of this RF amplifier is foreseen to be included in the project. Testing of the developed system can be done with the RF system testing station at SLRI.
                       Tools to be used: the RF circuit design tools, RF components design tools (CST Studio Suite). RF measuring tools are also available at SLRI.
                       Skill to be built: Candidate will gain skill and knowledge of the RF circuit design and microwave engineering. Programing and controlling skills will also gain during the process of building the control of the amplifier system.
