Rohde & Schwarz and Sivers Semiconductors have joined hands to test RF transceivers for 5G NR up to 71 GHz to address new testing challenges related to the bandwidth extension and to evaluate the performance of the latest generation RF transceiver chipsets.
Erik Öjefors, Chief Technology Officer of the wireless business unit at Sivers Semiconductors, says: “This has been a valuable opportunity for Sivers Semiconductors to be able to provide yet another proof point of our world-leading mmWave technology. Together with Rohde & Schwarz, we have demonstrated that the high performance of our mmWave transceiver RFICs provides a pathway for future NR-U deployments in the 60 GHz band based on the upcoming 3GPP Release 17 standard. Early access to test and measurement solutions capable of addressing new and upcoming standards such as 5G NR in the 60 GHz band is critical for our mission to be at the forefront of technology development.”
Andreas Pauly, Executive Vice President Test & Measurement at Rohde & Schwarz, says: “Together with Sivers Semiconductors, we set another milestone for the wireless industry. With our innovative test and measurement solutions, we verify new functionalities within the 5G New Radio standard, demonstrating our continued commitment to our partners and customers. Through this, we enable them to develop cutting-edge technology that will make advanced use cases of 5G for consumers and enterprises a reality.”
With Release 17, 3GPP will extend the frequency support for its 5G New Radio (5G NR) standard to 71 GHz by Mid-2022.
Rohde & Schwarz and Sivers Semiconductors have jointly tested the performance of the latest generation of RF transceiver chipsets, which so far supported the IEEE 802.11ad and 802.11ay standards, against 5G NR signals up to 71 GHz.
For the joint testing efforts, Sivers Semiconductors provided an evaluation kit as a device under test (DUT), powered by the state-of-art Radio Frequency Integrated Circuit (RFIC) TRXBF01 and the RF antenna module BFM06010. The RFIC supports IEEE 802.11ad/ay modulations up to 64QAM over the full frequency range from 57 to 71 GHz.
The setup consisted of the R&S SMW200A vector signal generator, which supports frequencies up to 67 GHz – 72 GHz in over range mode – thanks to a new frequency option, and the R&S FSW85 signal and spectrum analyzer, the only one with an integrated signal analysis bandwidth of up to 8.3 GHz and supporting RF frequencies up to 90 GHz.
The R&S ATS1800C compact antenna test range (CATR) based 5G NR mmWave test chamber completed the setup for over-the-air (OTA) testing.
