TCL picks Keysight to accelerate 5G device validation
Integrated OTA test system supports scalable over-the-air mmWave verification across multiple bands, antennas in 5G device manufacturing.

Keysight Technologies has announced that TCL Communication Technology Holdings Limited (TCL) selected its integrated mmWave over-the-air (OTA) test system to accelerate 5G device validation in manufacturing.

TCL, one of the world’s leading mobile phone makers measured in sales volume, has expanded its use of Keysight 5G device test products to gain access to mmWave OTA wide-band non-signaling test capabilities. These include verifying key parameters such as transmitter output power levels and ratio of power leaking into adjacent channels. Keysight’s compact, integrated system enables TCL to address a wide range of manufacturing test requirements by supporting multiple bandwidth options in frequency range 2 (FR2).

“We are pleased to provide TCL with 5G device test solutions across the workflow, from design and development validation to manufacturing test,” said Chih-Kai Wu, director of manufacturing solutions in Keysight’s wireless test business. “Keysight’s scalable mmWave test solution enables TCL to cost-effectively verify the performance of multiple devices in parallel, reducing test cycles in manufacturing.”

TCL designs 5G devices with wider bandwidth support in FR2, providing users access to advanced 5G applications that require wider bandwidths to quickly transfer large quantities of data between the device and the 5G base station.

“Keysight’s scalable and integrated 5G mmWave OTA device test solution enables TCL to flexibly verify a large volume of 5G devices with variable bandwidth support,” said Xu Dai, director of industry management center at TCL Communication. “High test throughput enables us to accelerate the validation process and confidently bring products to market that comply to our design specifications.”
