E-Learning Video Series Demonstrates RF Link Budget Analysis for Communication and Radar Systems

Feb 3, 2020


A new four-part AWR software e-learning video series demonstrates how to use Visual System Simulator™ (VSS) system simulation software and its impedance-mismatch aware, linear and nonlinear RF/microwave behavioral models to perform budget analysis. These design tools are useful for system architecture development and RF component specification for communications system design. The tutorials demonstrate how to:

  • Build a basic RF chain
  • Define the characteristics of the amplifier, filter, and mixer components using behavioral models based on parameter-defined, data file and subcircuit implementations
  • Perform budget analysis, including cascaded noise figure (NF), third-order intercept point (IP3), 1 dB compression point (P1dB), and more
  • Use spectral analysis to simulate spurious tones due to device nonlinearities

In the final video, a modulated signal utilizing a quadrature phase-shift keying (QPSK) signal generation source from the VSS library (which includes a comprehensive collection of communication standards such as 5G new radio [NR]) is passed through the RF link. The resulting modulated spectral response and eye diagram demonstrate the ability of VSS software to run concurrent time- and frequency-domain analyses.
