The transmisssion and matching system of the JET ITER‐Like ICRF antenna includes specific design features, contributing to tolerance of the generators to large (dominantly) resistive increases in loading, and to be tested on JET in ITER‐relevant ELMy H mode conditions for the first time. Beside the “conjugate‐T” circuit, internally matching the launcher to a very low reference impedance, an original adjustable wideband transformer has been designed for compatibility with various ancillary functions. Optional 3dB splitters provide futher generator isolation. The paper discusses design choices leading to the final layout and briefly presents the simulated performance of the system. © 2003 American Institute of Physics
