 A K-Band Low-Power Miniaturized Hyperthermia System Dong-Ki Kim, Ki-Hyun Kim, Jung-Min Oh, Young-Rak Park, Young-Woo Kwon Institute of New Media and Communications(INMC), School of Electrical Engineering and Computer Science, Seoul National University Abstract A K-band low-power miniaturized planar-type hyperthermia system was developed to replace massive and expensive equipment. The system consists of a VCO with a buffer amplifier, a high-power amplifier module, a 20-dB-coupled line coupler, a chip circulator and two power detectors for signal generation, amplification and power monitoring. All these components have been implemented in planar form on two module blocks. The total size of the hyperthermia system was less than $10times6.5times3;cm^3$. In order to verify the system performance, ablations were carried out on nude mice xenografted with human breast cancer. Ablation results show performance comparable to the massive components-based system. This work shows the feasibility of a low-cost miniaturized hyperthermia system for practical clinical applications. Key words: Hyperthermia, Ablation, Bio System
