Theoretical and Experimental Results of a Distributed Serial to Parallel and Parallel to Serial Converter for Gigabit Rates

This paper presents experimental and theoretical results of an application of the SSL-principle (Series-gate Sampling Line) to the regeneration of fast digital signals. As demonstrated below this procedure allows high speed data processing at gigabit rates by means of a spatial parallel to serial and serial to parallel conversion using Schottky diodes as fast switches between pieces of microstrip lines for recording resp. generating signals bit by bit. Some results of a two years intensive theoretical and experimental investigation of the SSL-principle are shown including experiences with a laboratory model of a base-band repeater operating at 1.25 Gbit/s. Preliminary experimental results demonstrate that without big efforts the bit rate can be extended to 2.5 Gbit/s.
