“The SMW200A is the first to allow a flat frequency response and 2GHz modulating bandwidth above 44GHz,” the company said. “The option from 100 kHz to 56 GHz covers all currently used 5G frequencies, as well as the applied ground-satellite. The 100kHz to 67GHz option also supports planned higher frequency 5G bands, 60GHz WiGig band and inter-satellite connections.
The 2 GHz modulation bandwidth maintains the wider subcarrier distance defined for 5G FR2 Release 17.
“3GPP Release 17 has reached a well-defined stage, so developers will be looking for a signal generator to cover the extended FR2 frequency range from 52.6 GHz to 71 GHz,” R&S said. “SMW200A with 67GHz option supports up to 72GHz in over-range mode.”
IEEE 802.11ad carried Wi-Fi and wireless LAN up to 60GHz (57-71GHz) unlicensed bandwidth, direct and reverse satellite connections operate between 37.5 and 52.4GHz, and intersatellite connections use up to 66GHz with up to 2GHz bandwidth, he added.
The SMW200A is modular and can, for example, have a second RF path added, as well as a maximum of two baseband modules and four attenuation simulation modules. It can create signal scenarios such as 8 × 8 MIMO and LTE-Advanced media aggregation, including attenuation – when more than two RF paths are required, the company’s SGMA signal generator modules must be connected.
