Abstract:
An energy delivery system includes an RF synthesizer circuit configured to generate an RF electric signal and a preamplification stage operably coupled to the RF synthesizer circuit. The preamplification stage has at least one attenuator. A board controller is operably coupled to the attenuator of the preamplification stage that is configured to modify a gain setting of the attenuator. An output connection is configured to provide a low-power signal or a high-power signal based on at least the RF electric signal and the gain setting. The low-power signal or high-power signal is provided to an RF applicator configured to couple an alternating RF electric field to animal tissue.
