  The K-800 superconducting cyclotron has been in operation at Laboratori Nazionali del Sud for almost 25 years. It has been subjected to continuous upgrades and modifications since 1994: the RF couplers have been redesigned, the new dees have been changed from aluminium to copper, as has the new central region from radial to axial injection of the beam, the hybrid configuration solid state - tube of the power amplifiers, the digital LLRF, etc. The next scheduled important upgrade of the Cyclotron mainly consists in a new extraction beam line able to support the increase of the beam current intensity. The accelerated beam will be extracted in two ways: by stripper and by electrostatic deflector and, consequently, one of the most important features of the new upgrade is the new cryostat. Further upgrades and refurbishments of the other main parts of the cyclotron, such as a new liner, the modification of the RF cavities and dees, the refurbishment of HLRF-LLRF, the insertion of the stripper extraction system, to name but a few, are in progress, too. This work focuses on the RF system upgrade.
