Description	Journal: Journal of Physics: Conference Series Development of wideband solid state power amplifier in ITER [1] ICH&CD frequency range is ongoing. A 12 kW/CW Solid State Power Amplifire (SSPA) is being developed in house. 1 × 16 wideband splitter/combiner will be used at input/output side. Study has been carried out on two options i.e. coaxial type & lumped element based Wilkinson splitter/combiner. Tentative power level of both input N-Type ports of combiner is ~ 1 kW. Design and simulation for coaxial type Wilkinson combiner is done. Quarter wave length for centre frequency is ~ 1500 mm. To reduce mechanical dimension of combiner, PTFE dielectric is used with sophisticated arrangement. Coaxial combiner required unique fabrication process. Alternate option is proposed as a lumped element based Wilkinson combiner with reduced size, cost & development time. Design and simulation was carried out. Required PCB design & fabrication was done accordingly. Same design will be implemented for splitter as well. Design scheme for the splitter/combiner will be finalized depending on the achieved performance of both the designs. In this paper, detailed design, simulation and test results are presented for both types of combiners. A detailed comparison of combiners is provided.
