Engineers working on the validation of 5G mmWave beamforming devices in antenna test chambers must characterize their performance over the air (OTA). They need to configure and run detailed 3D spatial sweeps within a carefully controlled RF environment. However, conducting these spatial sweeps to plot 3D OTA antenna radiation patterns and calibrating beamformer codebooks are time consuming and expensive tasks. Furthermore, running these measurements over a range of temperatures adds a significant layer of complexity.
A solution for OTA validation of 5G mmWave antenna modules and beamforming devices must meet the following requirements:
Real-time, hardware-accelerated DUT positioner control for sampling thousands of points in space per minute (Azimuth and elevation)
Reliable narrowband and wideband (5G NR) OTA measurements, such as EIRP, TRP, and beam characteristics
Cost-optimized, high-isolation, low-loss CATR chamber for minimal signal interference and improved link budget
Characterization over temperature (-40°C to 85°C) with a modular thermal dome enclosure that avoids damage to the anechoic chamber
Optimized link budget and measurement coverage through direct far-field or a compact antenna test range (CATR) featuring a 20 cm quiet zone
Learn how NI’s 5G mmWave OTA Validation Reference Architecture speeds up detailed and accurate 3D sweeps of antenna patterns by five times or more to characterize and validate 5G mmWave beamforming designs in a fraction of the time.
