Rohde and Schwarz SMW200A vector signal generator

Rohde and Schwarz has introduced two maximum frequencies for the SMW200A vector signal generator, bringing performance to digitally modulated signals up to 67 GHz and beyond. The generator enables flat frequency response and 2 GHz modulation bandwidth above 44 GHz.

In addition to all applications already supported up to 44 GHz, the 100 kHz to 56 GHz option covers all currently used 5G frequencies, plus earth-to-satellite applications. The 100 kHz to 67 GHz option also supports planned higher frequency 5G bands, the 60 GHz WiGig band and inter-satellite links.

The vector signal generator now covers up to 67 GHz as a single-path instrument. A maximum modulation bandwidth of 2 GHz is supported, meeting the requirements of even the wider subcarrier spacings defined for 5G FR2 Release 17, and wideband satellite transmissions.

Applications in the U and V bands supported include mobile radio, wireless LAN and satellite communications, for mobile radio engineers developing RF components and products to support the 5G mobile radio spectrum available in the 47 GHz frequency band. Due to 3GPP Release 17, specifying further enhancements to 5G, the unit is suitable for developers looking for a signal generator to cover the now extended FR2 frequency range from 52.6 GHz up to 71 GHz.

The new frequency options are equally interesting for high-frequency Wi-Fi and wireless LAN, including IEEE 802.11ad, which operates in the 60 GHz unlicensed band (57–71 GHz). For satellite communication applications, forward and reverse links operate between 37.5 and 52.4 GHz; inter-satellite links use frequencies up to 66 GHz with bandwidths up to 2 GHz.

In addition, the unit is suitable for demanding applications above 44 GHz throughout the aerospace and defence industry, or for generating digitally modulated signals including early research on 6G components and systems.
