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
