Solid state RF power amplifiers have been considered as an attractive candidate for providing the high power RF power required in increasing number of accelerator applications in recent years. Due to the advantages of these amplifiers and based on the successful experience done in other light sources; ILSF RF group has started R&D in design and fabrication of solid state amplifiers. Two modules based on two different LDMOS transistors have been developed successfully at 500MHz. The measured characteristics are presented and compared in this paper. Combining of 8 such modules is under test to achieve 4kW output power as the first stage of the conceptually designed combining network. This paper outlines the design concept of the different parts of the amplifiers and presents the experimental results obtained so far.
