With climate change, scarcity of resources and the recent shortage of energy in general, sustainable and efficient technologies are ever more important for industrial applications, and also for research infrastructures.
Many large research infrastructures rely for their radio-frequency (RF) amplifiers on vacuum tube technology, a proven technology. However, the future of these tubes is not guaranteed, as the market is shifting towards solid-state technology. Solid State Power Amplifiers (SSPAs) offer many advantages compared to vacuum tube technology, such as: longer lifetime, longer mean time between failures, additional safety and redundancy in operation by combining multiple SSPAs, thus reducing limitations related to the one point of failure, as it would be the case with a vacuum tube device.
Many SSPAs need to be combined in order to produce the hundreds of kilowatts RF power levels required for particle accelerator applications. Power combination is a key factor enabling the economic competitiveness of such systems. The power combiners are thus an important component to be developed together with highly efficient SSPAs and integrating redundant operational configuration.
Different highly efficient SSPAs modules at high frequencies (HF) will presented - kilowatt level with efficiencies higher than 80% - as well as high power combiners at 10kW, 100kW levels and beyond.
