Keysight has announced a collaboration with Ball Aerospace and Anokiwave to validate the first commercial 5G NR active array antenna product designs in the 26 GHz band. The Keysight 5G NR-ready measurement testbed offers the precision that base station and component designers require to extensively explore the performance edges of a new class of active antenna systems in the “European Pioneer Band.”
The use of phased arrays at mmWave frequencies requires over-the-air (OTA) testing as well as spatial beam measurements. Keysight metrology-grade test equipment offers the sensitivity that base station designers need to overcome these challenges and to go beyond simple RF parametric performance. New spatial measurement requirements include sidelobe levels, dynamic beam characteristics, and spatial variations of EVM and ACPR.
As the first mmWave testbed with 5G-ready source and analyzer inside a PXI chassis, the Keysight solution is scalable across the product lifecycle, from research and development through manufacturing, using modular hardware and software. The 5G NR-ready testbed enables multi-format testing in a single chassis for space-efficient and flexible design validation, even at mmWave.
The Ball Aerospace-built 256-element array uses Anokiwave integrated circuits, and was designed to deliver 5G modulation in GHz-wide bandwidths in either a single-beam mode or in MIMO applications for up to 4 concurrent beams with up to +60 dBm EIRP.
At Mobile World Congress 2018, Keysight will be demonstrating the 5G Testbed for Design Validation making over-the-air (OTA) measurements of the new Ball Aerospace phased array antennas for 26 GHz and 28 GHz.
