Achieve Ultrafast mmWave OTA Validation Test

Engineers working on new 5G mmWave Antenna-in-Module (AiM) device validation must characterize beamforming performance over the air (OTA). With no access to traditional connectorized test ports to assess device performance, they need to configure and run detailed 3D spatial sweeps within a carefully controlled RF environment. Conducting these spatial sweeps can be extremely time consuming and expensive to perform.


A solution for mmWave OTA validation of beamforming devices must meet the following requirements:


  • Provide a cost-effective, quiet, and carefully controlled OTA test environment that includes enough link budget while minimizing measurement uncertainty
  • Accommodate devices under test (DUTs) of various sizes, from small AiMs with a few antenna elements to system-level designs with larger antenna arrays
  • Give engineers fast and detailed measurement results and plots
  • Simplify and speed up the process of configuring and running extensive, automated OTA test sequences

5G mmWave OTA Validation Reference Architecture

  • Reduce OTA validation times from hours to minutes by sweeping the 3D space in a continuous motion, using the PXI platform to synchronize the DUT positioner with the RF generation and analysis engine.
  • Obtain reliable narrowband and wideband (5G NR) OTA measurements, such as EIRP, TRP, and beam characteristics. Also acquire and visualize spatial results for EVM, ACLR, CHP, and SEM, using 3GPP-compliant 5G waveforms and channel bandwidths.
  • Optimize link budget and measurement coverage for various types of antenna modules and beamforming system designs by converting the OTA chamber into a compact antenna test range (CATR) featuring a 20 cm quiet zone.
  • Easily configure extensive spatial sweeps to characterize DUT antenna patterns while rapidly producing, visualizing, storing, or distributing detailed parametric results using NI’s mmWave OTA Validation Software.
