	As a major part of the BRIF project, the 100 MeV high intensity cyclotron being constructed at CIAE, CYCIAE-100, will provide 200 μA proton beam ranging from 75 MeV to 100 MeV for RIB production. Two identical 100 kW RF amplifiers will be used to drive two cavities independently to accelerate H⁻ beam up to 100 MeV. The detail technical specification has been investigated, fixed, and initial design has been finished by CIAE. Then, the construction design and manufacture is implemented by China Academy of Aero and Space, and the on site commissioning is successful by mutual efforts. The final commissioning is under way with a full scale prototype cavity at CIAE. A general description of the CYCIAE-100 RF system design will be given, as well as the review of 100 kW amplifier design. In the commissioning of the amplifier with dummy load, different high order resonances are found when operated at different frequencies between 42 MHz to 46 MHz. An equivalent circuit model is carried out to hunt down the problems. The model and related analysis will be reported together with the process and results of high power test with the cavity load through ~35 meters six inch rigid transmission line.
