Rohde & Schwarz has presented a compact test setup for generating and analysing signals up to 67 GHz at the 5G Global Summit in Busan, South Korea. The test setup consists of the up to 20 GHz 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 analyser.
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 analyses signals in the frequency range up to 67 GHz at an analysis bandwidth of 500 MHz and offers a 2 GHz analogue IF output for further analysis of broadband signals.
