Rohde & Schwarz achieves breakthrough in sub-THz research with 140 GHz multi-channel transceiver characterization

10/23/2024

Devices supporting mmWave frequencies, antenna systems and RF transceiver modules for future mobile communications standards or automotive radar applications will share the same characteristics that make them challenging to test. The wide frequency range, greater number of antenna elements and lack of conventional external RF connectors will require testing over-the-air in a shielded environment.

Doctoral candidates Ethan Chou and Hesham Beshary of Professor Ali Niknejad’s Berkeley Wireless Research Center (BWRC) at the University of California, Berkeley, in collaboration with test experts from Rohde & Schwarz, recently conducted tests using the new Rohde & Schwarz D-band over-the-air (OTA) characterization chamber. The tests took place at the Rohde & Schwarz lab in Coppell, TX, where the group evaluated the chips and application boards, they designed and fabricated.

The test setup consisted of the R&S ATS1800C OTA antenna test system, the R&S FSW50 signal and spectrum analyzer, the R&S SMW200A vector signal generator, the R&S SMB100A signal generator for PLL reference, the R&S NGP800 and NGL200 power supplies, and the R&S AMS32 antenna measurement software.
