Engineers working on new 5G mmWave Antenna-in-Package (AiP) devices have the tough test challenge of characterizing the beamforming performance of these devices over-the-air (OTA). With no access to traditional connectorized test ports to assess device performance, engineers need to configure and run detailed 3D spatial sweeps within a carefully controlled RF environment in an anechoic chamber. Conducting these spatial sweeps can become a very time-consuming and prohibitively expensive task.
A test solution for mmWave OTA validation of AiP devices must meet the following requirements:
- Provide a cost-effective, quiet, and carefully controlled OTA test environment
- Give engineers fast and detailed measurement results and plots
- Reduce OTA measurement uncertainty through proper system calibration
- Simplify the process of configuring and running comprehensive, automated OTA test sequences
