Noise radars use random or pseudo-random signals to illuminate a target and coherent detection techniques in order to process received noise signals. In the range of microwave frequencies the simple analogue systems of the correlative detector may be used. It helps to overcome the fact that the real digital implementation of the autocorrelation function for these frequencies is very difficult. A correlator receiver is a typical element of the noise radar. The important issue is that coherent reception needs delay lines of constant or variable parameters to be applied in the receiving systems. To address this issue the paper comprises comparison of available technologies of microwave analogue delay lines. The advantages and disadvantages of presented solutions are presented. The paper comprises: the types of basic delay unit technologies, tunable and controlled-delay lines.

“…The trapezoidal shape allows a good channel performance, reducing insertion and return losses [3], however, their implementation can be difficult in dense routing areas (e.g., close to the pinout). Serpentine shapes show a similar performance [4], however, their physical area for implementation is even larger and more problematic.…”

This work presents a Python-based driver for ANSYS HFSS for length matching elements (LME) implemented in Matlab. The driver allows full-wave EM parametric simulation of length matching elements, whose S-parameters are inserted in other circuit simulators, such as ADS, for a complete interconnect validation. Three different LME (i.e., trapezoidal, triangular, and rectangular) are analyzed using the driver in a common highspeed routing scenario. The driver proposed in this work allows verifying that the three LME considered have a similar performance up to 5 GHz, indicating that these LME can be used as mismatch (phase skew) compensation structures in some interfaces within this frequency band, such as USB 3.0, PCIe Gen3 or 1 GBASE Ethernet. On the other hand, the trapezoidal LME shows the best performance for frequencies higher than 5 GHz, with a low impact in the electromagnetic interference (EMI), making it the most recommended for high-speed interfaces with operating frequencies higher than 5 GHz.
