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