Rohde & Schwarz, Fujikura, and Avnet validate CATR OTA test systems for 5G mmWave phased array antenna R&D testing

Fri 09, 06 2023

Rohde & Schwarz has partnered with Fujikura and Avnet to validate their new development kit for 5G mmWave phased array antenna modules (PAAMs). This collaboration aims to enable system architects to prototype and optimize tuning parameters for 5G mmWave systems using AMD Xilinx’s Zynq UltraScale+ RFSoC Gen3 and Fujikura’s FutureAcess Phased Array Antenna Module.

As part of the collaboration, Rohde & Schwarz has worked with Avnet to integrate remote controls for Rohde & Schwarz test instruments into the Avnet RFSoC Explorer software. This integration allows for the control of the entire signal chain from baseband to mmWave and automates mmWave measurements with a single graphical user interface and application programming interface.

Fujikura has validated the R&S ATS800B benchtop CATR OTA test system from Rohde & Schwarz for research and development (R&D) testing of 5G mmWave phased array antennas. The R&S ATS800B offers accurate and repeatable measurement results while providing easy access to the Device Under Test (DUT). This capability is particularly valuable during the early stages of design and verification when the product is still in an R&D open setup.

The R&S ATS800B setup also allowed Fujikura to perform simultaneous measurements of their PAAM in horizontal and vertical polarizations, thanks to the R&S TC-TA85CP cross-polarized Vivaldi antenna used as a feed antenna. In the next phase of collaboration, Fujikura plans to validate the R&S ATS800R, a rack-mountable anechoic CATR chamber, to obtain more accurate 3D EIRP patterns and understand heat dissipation during measurements.

The advanced mmWave and OTA test solutions from Rohde & Schwarz facilitate the design and prototyping of phased array antenna modules for 5G FR2 systems. In June, Rohde & Schwarz, Fujikura, and Avnet will host a joint workshop on validation with the R&S ATS800B at the IMS 2023 in San Diego. The workshop will provide attendees with the opportunity to evaluate PAAM configurations and perform various measurements for evaluation.
