ABSTRACT:
A dispersive delay line and method for fabricating the delay line is described in which coaxial cable is utilized and in which the dispersive or bandpass characteristic is established by the crimping of the coaxial cable in such a manner that the axial crimp length is small compared to the wavelength, thereby providing a discontinuity which behaves like a simple shunt capacity. A simple fabrication technique is utilized in which the crimps are applied to the line at selected points by use of a four-tooth crimping tool.
