Abstract
A portable electrosurgical system () for treating biological tissue with microwave radiation (e.g. having a frequency between 500 MHz and 60 GHz) is disclosed. The system comprises a hand-held microwave sub-assembly () which generates and amplifies a microwave signal (which may be continuous or modulated) for treatment and includes a treatment antenna () for delivering the radiation. Diode detectors () in the sub-assembly () may detect forward and reflected power levels to enable determination of net delivered power. A dynamic impedance matching system may be provided to match energy developed by amplifiers () in the sub-assembly () to the biological tissue load. A tuning filter () and couplers () for extracting magnitude and phase information from the microwave signal are thus provided in the sub-assembly.
