Design and test of a 434 MHz multi-channel amplifier system for targeted hyperthermia applicators.


PURPOSE For our head-and-neck hyperthermia (HT) applicator, an amplifier system with full amplitude and phase-control to deliver the radio-frequency signals, was not available. We therefore designed and tested a 433.92 MHz multi-channel amplifier system. SYSTEM DESCRIPTION The design consists of a direct digital synthesizer (DDS) system that generates 12… (More)
