pSemi, a Murata company focused on semiconductor integration, has launched a free beta version of a software for viewing S-parameters. The pSemi sNpViewer allows for in-depth S-parameter viewing graphically. This comprehensive viewer includes Smith, polar, magnitude, phase and phase vs. amplitude charting. Time-domain analysis is also available.
S-parameters (Scattering Parameters) describe the input-output relationships between ports in a linear RF system. Specifically, at high frequency, it becomes essential to describe a given network in terms of phase and amplitude of a wave rather than voltage or current.
As an example of 5G complexity, in order to select the best combination of phase and amplitude settings for a given RF channel in a multi-element array, an engineer must analyze thousands of distinct S-parameter data sets to ensure the best performance. To do this over multiple frequencies makes it even more laborious. Trying to visualize the results is complicated. Trying to isolate the best setting is even more demanding. The pSemi sNpViewer allows users to perform this search through thousands of S-parameter files to determine and record optimal performance.
This LUT feature can be especially useful for 5G beamforming or for any other device where a phase and/or amplitude LUT is required.
