Powerful New Test Capabilities for Beamforming Circuits
Rohde & Schwarz and US-based aerospace test and measurement provider Marvin Test Solutions have created a turnkey production tester for beamforming integrated circuits (IC) used in 5G mmWave (FR2) and satellite communications, the companies announced on 9 July.
Beamforming is becoming a default concept in both the 5G and satellite communications domains, as well as being a common technology in the aerospace and defence industry. Cooperation between the two companies began when Marvin showed interest in the capabilities and specifications of the Rohde & Schwarz ZNBT40 multiport vector network analyser (VNA) as the basis for its TS 900e-5G production tester.
The new ZNBT40 enables fast, reliable and extensive verification and characterisation of beamforming ICs with typically 5, 9 or even 17 RF ports. It is a unique VNA with a frequency range from 100kHz-40GHz and a true multiport architecture. Besides testing multiport ‘devices under test’ (DUT), such as the beamforming ICs, it also allows parallel testing of multiple DUT, using up to 24 ports. The large number of ports makes it possible to characterise 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,” commented Marvin Test Solutions CEO, Stephen T Sargeant.
“Rohde & Schwarz has a strong and long-standing tradition in making high-quality instruments. We are happy to be cooperating with a dynamic test house like Marvin Test Solutions on creating industry-leading turnkey test and measurement solutions,” added Rohde & Schwarz Director of Product Management Vector Network Analyser, Alexander Keck.
