Rohde & Schwarz tests mm-wave applications at the 5G Global Summit

Rohde & Schwarz presented an extremely compact test setup for generating and analyzing signals up to 67GHz at the 5G Global Summit, held in Busan, South Korea 20-21 October 2014,

The test setup consisted of the up to 20GHz 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 20GHz and a wideband I/Q modulator with a bandwidth of 2GHz. The internal baseband section with an I/Q modulation bandwidth of 160MHz 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 (60GHz to 90GHz). The R&S FSW67 analyzes signals in the frequency range up to 67GHz at an analysis bandwidth of 500MHz and offers a 2GHz analogue IF output for further analysis of broadband signals, making it ideal for the challenging T&M tasks associated with the 5G development phase.

5G will not simply extend existing LTE/LTE-Advanced systems; 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 67GHz test solution presented by Rohde & Schwarz meets this requirement.
