Abstract
Abstract A pulse transformer uses a stripline to form the windings. In order to achieve symmetry and minimize reflections, the stripline is twisted at predetermined points in the winding so that the position of the stripline conductors relative to the core is changed. In one embodiment the stripline is twisted 180* each time it passes through the center of the toroidal core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A pulse transformer, including in combination, a magnetic core, stripline conductive means including first and second conductors formed of equal width bare electrical conductive strips mounted in a rectangular configuration, first insulator means slidably positioned between and in direct contact with said first and second conductors to hold the same in spaced-apart relationship, second insulator means disposed about said first and second conductors and said first insulator means in a restraining slidable engagement with said pair of conductive strips, said stripline conductive means being wound about said core and twisted so that said first and second conductors are alternately adjacent said core with the length of said first conductor adjacent said core being substantially equal to the length of said second conductor adjacent said core.
Claim 2
Dependent Claim
125 words
A pulse transformer, including in combination, a magnetic core, stripline conductive means including first and second conductors formed of equal width bare electrical conductive strips mounted in a rectangular configuration, first insulator means slidably positioned between and in direct contact with said first and second conductors to hold the same in spaced-apart relationship, second insulator means disposed about said first and second conductors and said first insulator means in a restraining slidable engagement with said pair of conductive strips, said stripline conductive means being wound about said core and twisted so that said first and second conductors are alternately adjacent said core with the length of said first conductor adjacent said core being substantially equal to the length of said second conductor adjacent said core.
Claim 3
Dependent Claim
37 words
The pulse transformer of claim 1 wherein, said stripline conductive means is wound about said magnetic core with a plurality of turns, said stripline conductive means further being twisted 180* in each of said plurality of turns.
Claim 4
Dependent Claim
23 words
The pulse transformer of claim 2 wherein, said conductive means is twisted at the same point in each of said plurality of turns.
Claim 5
Dependent Claim
52 words
The pulse transformer of claim 1 wherein, said magnetic core is a toroidal ferrite core, said stripline conductive means being wound about said core with a plurality of turns, each of said turns having said stripline conductive means twisted 180* as said stripline conductive means passes through the center of said core.
Claim 6
Dependent Claim
28 words
The pulse transformer of claim 1 wherein, said second insulator means is formed of a flexible cover surrounding said first and second conductors and said first insulator means.
Claim 7
Dependent Claim
101 words
The pulse transformer of claim 1 wherein, said second insulator means includes a pair of insulating strips each positioned adjacent and in direct contact with a separate one of said first and second conductors to position each of said first and second conductors between said first insulator means and one of said pair of insulating strips, said pair of insulating strips being in slidable engagement with said first and second conductors, said second insulator means further including cover means surrounding said first and second conductors, said first-insulator means and said pair of insulating strips and holding the same in desired relationship.
