Microwave energy transfer component for electrosurgical apparatus

A microstrip impedance transformer that permits efficient (i.e. low loss) coupling of a microwave feed line (e.g. a conventional 50 Ω coaxial cable) to an instrument cable, where the instrument cable has a lower impedance (e.g. in the range 12 to 14 Ω) and includes an internal passageway. The micros...

More Information
Summary:A microstrip impedance transformer that permits efficient (i.e. low loss) coupling of a microwave feed line (e.g. a conventional 50 Ω coaxial cable) to an instrument cable, where the instrument cable has a lower impedance (e.g. in the range 12 to 14 Ω) and includes an internal passageway. The microstrip impedance transformer is configured to perform impedance matching between the microwave feed line and the instrument cable in a manner that does not adversely affect a separate feed, e.g. for delivering fluid, into the internal passageway.
