Patent ID: 8150074

Claim:
An apparatus for providing an impedance matched connection between a power source and a load, the power source being operable to output signals having frequencies that are within a predetermined range, the apparatus comprising: a coaxial line having a predetermined characteristic impedance and including an inner conductor disposed about an axis of the coaxial line, an outer conductor disposed about the inner conductor, and an insulator disposed between the inner conductor and the outer conductor, the inner and outer conductors each having a first end electrically connectable to output terminals of the power source; and a compensation circuit having an adjustable impedance and having a first terminal that is electrically connected to a second end of the inner conductor of the coaxial line and to a first terminal of the load and having a second terminal that is electrically connected to a second end of the outer conductor of the coaxial line and to a second terminal of the load; the compensation circuit being sufficiently adjustable to attain, for a pulse having a rise time or a fall time associated with a further range of frequencies that is faster than those associated with the predetermined range of frequencies, a combined impedance of the compensation circuit and the load that is substantially equal to the characteristic impedance of the coaxial line.
