Description

PathWave System DesignPathWave System Design (SystemVue) 2021 is a major update release. It continues the focused effort to make system simulation usable by all levels of system engineers by connecting circuit design, RF system design, baseband design, and hardware test together in a single platform. It further advances phased array analysis including accurate antenna and RF modeling and improved speed. It offers updated platform capabilities and connections to other enterprise tools as well as enhanced features for Radar and EW, Cellular, and WiFi system designers.

Phased array antenna enhancements

  • Sum-of-powers technique offers up to 10x speed improvement on high-density arrays
    • Regions of fine resolution can be specified for enhanced accuracy
  • Far Field IO (FFIO) format for direct antenna pattern import from EMPro/RFPro
    • Includes frequency dependent element patterns, coupling matrices
  • Sub-array architectures and array scaling from EM S-parameter subset
    • Patent-pending technique for simulation of large arrays with minimum EM data
    • Custom mapping of element patterns
    • Multi-beam antenna pattern support

Phased Array enhancements for directivity and sub-arrays

Phased array channel-specific amplifier parameters

  • Supports diversity of channel noise and distortion, including tapering

EM_Link: RF Board-level impairments from PCB designs

  • Import PCB designs into RFPro and then bring EM results easily into SystemVue
  • Adds board-level impairment to RF system simulation
