Perry.

Check out Tensolite Accuphase. It works to 40ghz last I heard. They make cables 
for testing products with 35ps TDR test equipment.  We did a test box for 65 
channel cable product and used this cable in the test unit and it did a fine 
job up to 35ps. 

Tensolite is now Carlisle Interconnect Technologies.  They make probes and 
cables for Tektronix, Agilent and Boeing so its good quality stuff.

Good luck
