Experimental Validation of a System-Level Model for Active Arrays Under Emulated Beam Steering
This work validates a behavioral modeling and measurement-based emulation framework for active phased arrays (APAs). Dataset collection time for power amplifier (PA) modeling is minimized using fast active load–pull, while validation employs measurement-based APA emulation to replicate beam steering operating conditions. Simulations closely match the measurement-based emulation of a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$2 \times 2$</tex-math> </inline-formula> patch-antenna APA for a 64-QAM orthogonal frequency-division multiplexing (OFDM) signal at 27 GHz across a wide range of beam angles, demonstrating the framework’s effectiveness for APA design and analysis.
