Abstract
Design details for a 0.5 to 4 GHz tracking delay for the Owens Valley Millimeter Array are presented. The delay uses a binary sequence of se gments ranging from 512 ns to 1/128 ns to provide any delay value up t o 1 mus with a maximum error of 7 ps. The segments are realized in opt ical fiber, coaxial cable and microstrip transmission line.
