“…There are several types dispersion delay line have been widely used and reported. The most common ones are dispersion fiber and surface acoustic wave dispersion delay line [7,8,9]. Both of them have the advantages in terms of large time-bandwidth product and compact sizes, however, these DDLs are not suitable for fully electromagnetic systems due to their operation frequency.…”

This paper deals the generation of chirped delay (CD) effect in microwave regime. For the purpose of achieving reflection dispersion, electromagnetic band-gap (EBG) structures with different rejection frequency are fabricated in different position by modulating the thickness of substrate. Microwave with different frequency will be reflected in different position, so non-flat reflected group delays responses can be obtained. One CD-EBG with 6-10 GHz operation frequency range is designed, fabricated and measured. Different group delay responses are obtained when feeding from different ports. Finally, temporal characteristic of the CD-EBG is studied by simulation and two chirped impulses are obtained.

“…Radio-Analog Signal Processing (R-ASP) has recently emerged as a new paradigm for monitoring, manipulating and processing radio signals in real time [1]- [3]. Compared to conventional Digital Signal Processing (DSP) techniques, R-ASP operates on signals directly in their pristine analog form to execute specific operations enabling microwave or millimeter-wave and terahertz applications.…”

Abstract-Generalized coupled-line all-pass phasers, based on transversally-cascaded (TC), longitudinally-cascaded (LC) and hybrid-cascaded (HC) coupled transmission line sections, are presented and demonstrated using analytical, full-wave and experimental results. It is shown that for N commensurate coupled-line sections, LC and TC phasers exhibit N group delay peaks per coupled-line section harmonic frequency band, in contrast to the TC configuration, which exhibits only one peak within this band. It is also shown that for a given maximum achievable coupling-coefficient, the HC configuration provides the largest group delay swing. A wave-interference analysis is finally applied to the various coupled-line phasers, explaining their unique group delay characteristics based on physical wavepropagation mechanisms.Index Terms-Dispersion engineering, group delay engineering, phasers, C-sections, D-Sections, all-pass networks, radioanalog signal processing (R-ASP).

“…Analog signal processing involves the manipulation of broadband analog signals in real-time via rearrangement of their frequency components in time [1]. Because of their analog nature, microwave analog signal processors are typically passive systems, which are inherently broadband, fast, frequency scalable, and power efficient, as compared with their digital counterparts.…”

“…Because of their analog nature, microwave analog signal processors are typically passive systems, which are inherently broadband, fast, frequency scalable, and power efficient, as compared with their digital counterparts. The core component of an analog signal processor is a phaser 1 [6], which may essentially be seen as a phase filter, where different temporal frequencies travel with different phase and group velocities or delays. The core component of an analog signal processor is a phaser 1 [6], which may essentially be seen as a phase filter, where different temporal frequencies travel with different phase and group velocities or delays.…”

A closed-form iterative procedure for synthesizing quasi-arbitrary phase responses with cascaded microwave C-section all-pass phasers is presented. The synthesis consists in mapping the transmission poles of the cascaded C-section structure onto the transmission poles of the specified transfer function, where the latter poles are computed using a closed-form polynomial generation method. The real and complex transmission poles of the specified transfer function are realized using C-sections of different lengths and different couplings coefficients. The proposved synthesis is validated by both full-wave analysis and measured multilayer prototypes.
