Keysight Technologies on Wednesday announced that TCL Communication Technology (TCL) selected the company’s integrated mmWave over-the-air (OTA) test solution to accelerate 5G device validation in manufacturing.
TCL, one of the world’s leading mobile phone makers measured in sales volume, has expanded the company’s use of Keysight 5G device test solutions 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 solution enables TCL to address a wide range of manufacturing test requirements by supporting multiple bandwidth options in frequency range 2 (FR2).
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 mmWave OTA test solution for 5G device validation in manufacturing combines the E6681A EXM-WB Wireless Test Set with one or several M1740A remote radio heads (RRHs) and a rack-mounted test chamber (RMTC). Users can easily upgrade bandwidth support, from 300MHz to 1.2GHz, to meet test requirements for mmWave devices up to 43.5GHz, equipped with wider bandwidths of 200MHz and 400MHz. Keysight’s mmWave transceiver RRHs support flexible signaling and non-signaling bi-directional testing across any 3GPP-defined band in FR2.
