A reflection-type artificial dielectric substrate (ADS) microstrip dispersive delay line (DDL) for analog signal processing is presented. This DDL is realized by nonuniformly alternating conventional and ADS microstrip sections with a linearly increasing period (linear group delay or constant chirp) so that the different spectral components of a modulated signal incur different delays proportional to their frequency to be discriminated in time. Design guidelines are provided. The proposed DDL… CONTINUE READING
