Turnkey production tester for 5G beamforming chips
Rohde & Schwarz has teamed up with Marvin Test Solutions to create a turnkey test system for beamforming chips used in 5G mmWave (FR2) and satellite communications.

Beamforming is becoming a default concept in 5G NR and satellite communications, so the two companies worked on a new production tester, the TS 900e-5G, based on the new R&S ZNBT40 multiport vector network analyzer (VNA) from Rohde & Schwarz.  

The ZNBT40 is a multiport VNA enabling fast, reliable and extensive verification and characterization of 5G beamforming ICs with typically 5, 9 or even 17 RF ports. It is a unique vector network analyzer with a frequency range from 100 kHz to 40 GHz and a true multiport architecture. Besides testing multiport devices under test (DUT) like the 5G beamforming ICs, it also allows parallel testing of multiple DUTs using its up to 24 ports. The large number of ports makes it possible to characterize a beamforming IC in full detail and see the cross-correlation effects while monitoring all antenna connections.

"For the heart of our test set we selected the Rohde & Schwarz R&S ZNBT40 vector network analyzer over the competition due to its unique, cutting-edge capabilities. Our collaboration with Rohde & Schwarz enables our two companies the opportunity to deliver the best available solution to meet customers' demanding requirements," said Major General Stephen T. Sargeant, CEO of Marvin Test Solutions.

The TS 900e-5G production tester is available from Marvin Test Solutions.
