An electrical connector having at least four electrical contacts that form two pairs of differential signal contacts. The first and second electrical contacts may be arranged edge-to-edge along a first direction. The third electrical contact may be adjacent to, and arranged broadside-to-broadside with, the first electrical contact along a second direction substantially transverse to the first direction. The first and third electrical contacts may define one of the pairs of differential signal contacts. The fourth electrical contact may be adjacent to, and arranged broadside-to-broadside with, the second electrical contact along the second direction. The second and fourth electrical contacts may define the other pair of differential signal contacts. The two pairs of differential signal contacts may be offset from one another along the second direction.

What is claimed: 1. An electrical connector comprising: an array of electrical contacts extending along a plurality of rows and columns, wherein each of the columns is spaced apart from an adjacent column by a constant column pitch, and the array of electrical contacts includes: a first electrical contact disposed in a first column and a second electrical contact disposed in a second column adjacent the first column, wherein the first and second electrical contacts are disposed in a first row and are arranged broadside-to-broadside so as to define a first broadside coupled differential signal pair; a third electrical contact disposed in the second column and a fourth electrical contact disposed in a third column adjacent the second column, wherein the third and fourth electrical contacts are disposed in a second row adjacent the first row, and the third and fourth electrical contacts are arranged broadside-to-broadside so as to define a second broadside coupled differential signal pair; and a fifth electrical contact disposed in the first column and a sixth electrical contact disposed in a fourth column adjacent the first column, wherein the fifth and sixth electrical contacts are disposed in a third row adjacent the second row, and the fifth and sixth electrical contacts are arranged broadside-to-broadside so as to define a third broadside coupled differential signal pair. 2. The electrical connector of claim 1 further comprising a first non-air dielectric disposed between the first and second electrical contacts of the first pair of differential signal contacts and a second non-air dielectric disposed between the third and fourth electrical contacts of the second pair of differential signal contacts. 3. The electrical connector of claim 2, wherein at least one of the first or second non-air dielectrics include a plastic material. 4. The electrical connector of claim 2, wherein the first and second electrical contacts are housed in a first leadframe assembly and a second leadframe assembly, respectively, and wherein the first non-air dielectric is molded independent of the first and second leadframe assemblies. 5. The electrical connector of claim 1 further comprising: a first ground contact disposed in the first column and in the second row adjacent the first electrical contact and the third electrical contact, and a second ground contact disposed in the second column and in the third row adjacent the third and fifth electrical contacts. 6. The electrical connector of claim 5, wherein a broadside of at least one of the first and second ground contacts is longer along the first direction than a broadside of at least one of the first and third electrical contacts. 7. The electrical connector of claim 1, wherein the first and third electrical contacts are arranged in a direction that defines an oblique angle with respect to the first column. 8. The electrical connector of claim 1, wherein the electrical connector is devoid of shields. 9. The electrical connector of claim 1, wherein the first electrical contact includes a first mating end and a first terminal end and defines a first contact length therebetween, wherein the second electrical contact includes a second mating end and a second terminal end and defines a second contact length therebetween, and wherein the first and second contact lengths are substantially equal. 10. The electrical connector of claim 1, wherein at least one of the first and second pairs of differential signal contacts has less than a −0.5 dB insertion loss up to a frequency of 20 GHz. 11. The electrical connector of claim 1, wherein at least one of the first and second differential signal pairs has approximately zero suck out in a range of 0 to 20 GHz. 12. An electrical connector comprising: a first linear array of electrical contacts extending along a first direction, wherein the first linear array comprises a first electrical contact and an adjacent second electrical contact arranged broadside-to-broadside so as to form a first signal pair; and a second linear array of electrical contacts adjacent the first linear array and extending along the first direction, wherein the second linear array comprises a third electrical contact and an adjacent fourth electrical contact arranged broadside-to-broadside, wherein the third and fourth electrical contacts form a second signal pair, wherein the first and second signal pairs are offset from one another along the first direction, and wherein the second electrical contact and the third electrical contact are arranged edge-to-edge in a second direction substantially perpendicular to the first direction. 13. The electrical connector of claim 12 further comprising: a first non-air dielectric disposed between the first and second electrical contacts; and a second non-air dielectric disposed between the third and fourth electrical contacts. 14. The electrical connector of claim 13, wherein the first and second electrical contacts are housed in a first leadframe assembly and a second leadframe assembly, respectively, and wherein the first non-air dielectric is formed as part of at least one of the first or second leadframe assemblies. 15. The electrical connector of claim 12 further comprising a ground contact adjacent the first electrical contact along the second direction and adjacent the third electrical contact along the first direction. 16. The electrical connector of claim 15, wherein the ground contact is arranged edge-to-edge with the first electrical contact, and wherein the ground contact is arranged broadside-to-broadside with the third electrical contact. 17. The electrical connector of claim 15, wherein a broadside of the ground contact is longer along the second direction than a broadside of at least one of the first and third electrical contacts. 18. The electrical connector of claim 12, wherein the electrical connector is devoid of shields. 19. The electrical connector of claim 12, wherein the first signal pair is a first differential signal pair, and the second pair is a second differential signal pair. 20. The electrical connector of claim 12, wherein at least one of the first or second differential signal pairs is configured to minimize signal skew. 21. An electrical connector comprising: a first linear array of electrical contacts defining a first contact pattern along a first direction; a second linear array of electrical contacts adjacent the first linear array, wherein the second linear array defines a second contact pattern along a second direction opposite the first direction, and wherein the first and second contact patterns are substantially the same; a third linear array of electrical contacts adjacent the second linear array, wherein the third linear array defines a third contact pattern along the first or second direction, wherein when the third contact pattern is taken along the first direction, the third contact pattern is different from both the first and second contact patterns, and when the third contact pattern is taken along the second direction, the third contact pattern is different from both the first and second contact patterns; and wherein the each of the first, second, and third linear arrays comprises a ground contact and a signal contact. 22.
