Abstract
A medical apparatus operable to induce localized hyperthermia in a patient via an electromagnetic field emitted by an antenna of an applicator connected to an output of the medical apparatus includes a signal generator, a bidirectional coupler, and a controller. The signal generator generates a radio frequency signal as a function of an operating parameter to a single cable to an applicator. The bidirectional coupler provides the radio frequency signal generated by the signal generator to the output and receives a reflected signal from the output at the applicator. First and second low pass filters isolate the radio frequency signal and reflected signal from a temperature sensing signal transmitted via the single cable to at least one temperature sensor of the applicator.
