An electrical signal phase compensator includes at least two conductors and a ground wire. In a two conductor system, the length of the first conductor is substantially longer than the second conductor. The first conductor and the second conductor are connected in parallel, with the high frequency current in the first conductor and the low frequency current in the second conductor. In a three conductor system, the length of the second conductor is substantially longer than the third conductor which conducts an intermediate frequency. The second conductor is longer than the first conductor. The first conductor, the second conductor, and the third conductor are connected in parallel. The several conductors are mounted to minimize electromagnetic interaction. The electrical signal phase compensator may include a neutral line which is disposed adjacent to the corresponding signal line. Each respective neutral line is connected in parallel. Each end of the plurality of neutral lines is terminated with a potentiometer. Each potentiometer is connected to ground. The electrical signal phase compensator may also be implemented on a circuit board with spaced traces of different lengths. The high frequency conductor in all embodiments has a length which is at least 10 times or more the length of the low frequency conductor and preferably substantially longer to create the most significant compensation.
A multiple conductor electrical current phase compensator for carrying a broadband current from a source to an output device, comprising at least a first insulated conductor, said first insulated conductor being wound as a first coil with a plurality of superimposed abutting coil layers, each said layers of said first coil having first coil turns wound in a first direction and second coil turns wound in the opposite direction within each layer, a second insulated conductor connected in parallel with said first insulated conductor of said first coil and configured to be connected between said source and said output device, said second insulated conductor being wound as a second coil abutting said first coil and with a plurality of superimposed coil layers, each of said layers of said second coil having first coil turns wound in a first direction and second coil turns wound in the opposite direction within each of said coil layers of said second coil, said first insulated conductor having a first length for conducting said current and configured to carry relatively low frequencies of said current and said second insulated conductor having a second length greater than said first length by a factor of at least ten and configured to carry the higher frequencies of said current, said current at said output device being phase compensated to reflect the phase relationship of the relative low frequencies and high frequencies content at said source, and said first and second coils thereby wound to control the inductance of the coils and thereby minimize interaction between the first and second coils.
A multiple conductor phase compensator for a broadband current source configured to be connected to a load, comprising a first conductor wound on itself to form a first multilayer coil of wire configured to conduct a low frequency current, a second multilayer conductor wound on itself to form a second coil of wire configured to conduct a middle frequency current, and a third multilayer conductor wound on itself to form a third coil of wire configured to conduct a high frequency current, the length of wire in said third coil being substantially longer than the wire in said first and second coil by a factor of at least ten, each of said coils is wound as a multiple layer coil with at least a first layer having first coil turn in one direction and second coil turn wound in the opposite direction and a second layer with as having first coil turn in any direction and second coil turn wound in the opposite direction and said multilayer coils wound to control the inductance of the coils.
