Recent studies have shown that Gallium Nitride (GaN) and laterally-diffused metal-oxide semiconductor (LDMOS) semiconductor technologies are capable of delivering very high power level, opening up a new opportunity for replacing vacuum tubes at high power levels. The research on GaN and LDMOS amplifier design have been carried out to develop RF amplifier at kilowatt levels, most of them are still in the early stage and require to be investigated more on new technology.
Beside of researching on the SSPAs within the scope of this research, we will employ a novel RF signal combination method to enhance the efficiency of the power combiner. It will be also possible to establish the feasibility for different applications of high power RF power. This project provides a deep understanding of the design approaches of SSPA in medical scanners, which can open new windows towards enhancing medical technologies.
The significant impact of new competences and skills on future success of the researcher are assessed below.
1) The project will contribute to obtaining of fruitful knowledge regarding the structure of cyclotron and SSPA structures from existing literature. Since cyclotrons are the most sophisticated component of a PET and also are widely employed in other medical industries (e.g. in proton therapy or particle physics), this skill facilitates extending the researcher’s knowledge to other particle accelerator projects after the fellowship.
2) The project associated with the design and implementation of RF/Microwave amplifiers which is the main area of expertise of the researcher and the host. Since RF amplifiers are widely used in a variety of industries (e.g. medical, research, physics, broadcast, cellar cell, Wi-Fi, RF IDs, weather, space, military, oil, and elsewhere), this skill makes them more experienced for subsequent projects.
3) The project will improve both the host and the researcher’s ability in the design of other sophisticated components of high-power microwave devices such as splitter, combiners, and couplers. Understanding the design methodology of the passive sub-systems is a highly valuable skill, since they are employed in the different fields of science e.g. proton therapy for cancer subjects, meteorology and civil and geology radars.
4) The project will provide to the experienced researcher the best mobility experience, both in term of moving between European countries and switching between academic and industry sectors. This experience will enlarge the researcher profile and extend the opportunities for future work position at home or in industry.
