MediaTek powers Rohde & Schwarz’s high-performance turnkey OTA system to test challenges of 5G deployment
MediaTek and Rohde & Schwarz are joining hands to perform over-the-air (OTA) tests of MediaTek’s 5G frontend modules and antenna arrays. The R&S TS8980R&D-M1 test system, which includes the new R&S ATS1800C CATR (compact antenna test range chamber), will be used to fully characterize, verify and test the antenna performance of MediaTek’s 5G network solutions including its Helio M70 5G modem.
The Rohde & Schwarz solution is topmost in the industry to meet some of the major challenges of real-world 5G deployments. To give an instance, millimetre waves experience high path loss, and shadowing effects further decrease signal strength. The solution would be a beam forming antenna array design which demands a test environment capable of measuring multiple beam streams to ensure the required quality and characteristics of each beam.
R&S ATS1800C CATR chamber to safeguard 5G transmitters
Rohde & Schwarz supplies complete 5G mm Wave OTA turnkey solution using the R&S ATS1800C CATR chamber to safeguard repeatable, exact and strong characterization of 5G transmitters and receivers. The R&S ATS1800C CATR is a movable shielded chamber solution that allows engineers to fully characterize and test their components in a non-conducted OTA environment.
The R&S ATS1800C includes a highly accurate positioning system that allows for handling transmitter and receiver performance measurements in a 5G environment with beam formed signals, covering a wide frequency range of 20 to 87 GHz. Perform. Furthermore, it can accomplish blackbox 3D far field measurements of 30 cm devices (Smartphones, tablets, notebooks) while occupying an unrivalled footprint of only 1.4 m2 (15 sqft).
Mechanisms of the R&S TS8980R&D-M1 test system to examine 5G signals
The R&S TS8980R&D-M1 test system consists of the R&S ATS1800C CATR (compact antenna test range) chamber—along with the R&S SMW200A vector signal generator, R&S FSW50 signal and spectrum analyzer and R&S ZVA40 vector network analyzer.
The R&S SMW200A and R&S FSW are the first instruments of their kind to provide mm Wave frequencies and 2 GHz modulation/demodulation bandwidth. Moreover, the R&S ATS1800C is used with the R&S SMW200A vector signal generator to conduct device receiver tests. The R&S ZVA40 vector network analyzer supports up to four independent signal sources allowing parallel signal output. The R&S ZVA series is an ideal choice for demanding measurement tasks in the lab and in production.
Statement from General Manager of Wireless System Design and Partnership at MediaTek
JS Pan, General Manager of Wireless System Design and Partnership at MediaTek stated, “We’ve worked closely with Rohde & Schwarz over the past few years to accelerate the development of mm Wave technologies and optimize our solutions for 5G networks. Further he added, “Our tests on the Rohde & Schwarz OTA test system will ensure that our customers can confidently bring to market devices that meet the rigorous requirements of 5G.”
Statement from Vice President Systems and Projects of Rohde & Schwarz
Alexander Pabst, Vice President Systems and Projects of Rohde & Schwarz stated, “To deliver on the promise of high speed and reliable 5G connectivity, it’s essential to accurately measure and test antenna performance in an OTA environment. Our high-performance turnkey OTA system is ideally suited to help companies like MediaTek more quickly and reliably bring their solutions to market.”
