Multiple modulators are provided, a respective one of which corresponds to a respective one of the radio channel frequencies. Each modulator generates at least one constant amplitude, phase modulated drive signal at the corresponding radio channel frequency from the respective information modulation, such that the at least one constant amplitude, phase modulated drive signal corresponds to the information modulation for the corresponding radio frequency. At least one saturated power amplifier is provided for each of the at least one constant amplitude, phase modulated drive signals.

An ultrasound coupling device for acoustically coupling an ultrasound transducer with a patient's body comprises a fluid chamber having an ultrasound transducer interface for placing an ultrasound transducer in contact with water within said fluid chamber. The coupling device also has a patient interface comprising a water permeable membrane. The membrane has an internal membrane surface which is in contact with the water in the water tank and an external membrane surface can be placed in contact with the patient's body. The membrane is specially designed to allow water from inside the water tank to slowly permeate or “leak” to the external membrane surface while such surface is in contact or placed in very close proximity to the patient's skin. The slow permeation rate maintains the external membrane surface wet and free of air bubbles during a procedure which can take several hours. At the same time, the slow rate of permeation does not cause any water spillage around the patient.
