Rohde & Schwarz presents mm-wave 5G test setup

October 23, 2014. At the 5G Global Summit, held in Busan, South Korea, on October 20 and 21, 2014, Rohde & Schwarz presented a compact test setup for generating and analyzing signals up to 67 GHz. The test setup consists of the R&S SMW200A high-end vector signal generator, a harmonic mixer from subsidiary Radiometer Physics GmbH (RPG), and the R&S FSW67 high-end signal and spectrum analyzer. This test setup enables users to evaluate potential new physical air interface technologies for future 5G networks, helping to drive the development of components, antennas, and chipsets for future base stations and wireless devices. 

The R&S SMW200A features two integrated RF paths up to 20 GHz and a wideband I/Q modulator with a bandwidth of 2 GHz. The internal baseband section with an I/Q modulation bandwidth of 160 MHz supports all digital communications standards, with the option to add fading simulators as needed. The integrated ARB generator can be used to generate high-quality, complex, digitally modulated waveforms. In combination with RPG harmonic mixers, it is possible to generate signals for all relevant frequencies—for example, into the E band (60 GHz to 90 GHz). The R&S FSW67 analyzes signals in the frequency range up to 67 GHz at an analysis bandwidth of 500 MHz and offers a 2-GHz analog IF output for further analysis of broadband signals, making it suitable for the challenging T&M tasks associated with the 5G development phase.

5G will not simply extend existing LTE/LTE-Advanced systems, the company reported—it will also create a new technological framework to support a variety of different application scenarios and a sharp increase in the number of wireless devices. One way to meet the demand for more system capacity and higher data rates is to extend the spectrum into the millimeter-wave range. The up-to-67-GHz test solution presented by Rohde & Schwarz meets this requirement.

Rohde & Schwarz is a Gold Sponsor of the 5G Global Summit in Korea and a member of the 5G Forum in Korea. Rohde & Schwarz also supports the 5G Lab Germany and is active in numerous 5G initiatives around the world, including the 5G Innovation Center in Surrey, UK, the Future Forum in China and the NGMN 5G Initiative in Germany.
