Abstract
Various embodiments of an apparatus, circuit board, and method are disclosed for cable termination. In one embodiment, a surface pad is disposed on a surface of the circuit board. A ground conductor is in the circuit board, the ground conductor being parallel to and collateral to the at least one surface pad. Also, at least one antipad is positioned between the at least one surface pad and the ground conductor, wherein a nonconductive volume extends from the surface pad to the ground conductor through the at least one antipad.

A circuit board, comprising:
- a surface pad on a surface of the circuit board;
- a ground conductor in the circuit board, the ground conductor being parallel to and collateral to the at least one surface pad;
- and
- at least one antipad positioned between the at least one surface pad and the ground conductor, wherein a nonconductive volume extends from the surface pad to the ground conductor through the at least one antipad.
An apparatus for launching a signal into a cable, comprising:
- a circuit board having a surface pad on a first surface of the circuit board;
- a first ground conductor in the circuit board, the first ground conductor being parallel to and collateral to the at least one surface pad;
- at least one antipad positioned between the at least one surface pad and the ground conductor, wherein a nonconductive volume extends from the surface pad to the ground conductor through the at least one antipad;
- a second ground conductor disposed on a second surface of the circuit board, the second ground conductor being electrically coupled to the first ground conductor;
- a first cable conductor of the cable being coupled to the surface pad;
- and
- a second cable conductor of the cable being coupled to the second ground conductor.
A method for launching a signal into a cable, comprising:
- electrically coupling a first cable conductor of the cable to a surface pad on a circuit board;
- electrically coupling a second cable conductor of the cable to a first ground conductor on a surface of the circuit board;
- and
- minimizing an impedance mismatch between the cable and the circuit board by providing a second ground conductor in the circuit board, the second ground conductor being parallel to and collateral to the surface pad, and providing at least one antipad positioned between the surface pad and the second ground conductor, wherein a nonconductive volume extends from the surface pad to the second ground conductor through the at least one antipad, and the first ground conductor is electrically coupled to the second ground conductor.
A circuit board, comprising:
- surface pad means for mounting a first conductor of a cable on a surface of the circuit board;
- a ground conductor in the circuit board, the ground conductor being parallel to and collateral to the at least one surface pad;
- and
- means for minimizing an impedance mismatch between the cable and the circuit board including at least one antipad positioned between the at least one surface pad means and the ground conductor, wherein a nonconductive volume extends from the surface pad mean to the ground conductor through the at least one antipad.
