	Cylindrical array of independently phased dipoles is suggested for hyperthermia of deep-situated tumors as a kind of treatment of cancer coupled with other methods such as radiation therapy and chemotherapy. It was proposed to focus the maximum of electromagnetic field at the site of tumor to produce high efficiency heating of tumor and to prevent overheating of surrounding healthy tissues. That's why we use system of independently fed dipole antennas. The operating frequency is 150 MHz. The independent feeding permits us to focus electromagnetic field producing by phased array in desirable area by means of changing of amplitudes and phases of each dipole. The RF power system schematic layout for 8 independently phased dipole antennas is presented. The control system of RF power system elements is considered. The software developing to provide choosing amplitude's and phase's values of dipoles are discussed.
