Fujikura Exhibits mmWave Products at MWC Barcelona 2025
Fujikura Ltd. announced that it will exhibit their mmWave products at MWC Barcelona 2025, the largest mobile industry exhibition to be held in Spain.
At this exhibition, they will exhibit wafer-level packaged 28 GHz beamformer ICs and frequency converter ICs, as well as a 28 GHz mmWave antenna board that incorporates these and integrates peripheral functions for the first time.
A live demonstration using a 60 GHz mmWave wireless communications module will also be held at the venue.
This exhibition will take place at booth 5C81 in Hall 5 at MWC Barcelona 2025, which will be held from March 3 to 6, 2025.
28 GHz mmWave antenna board
The newly developed 28 GHz mmWave antenna board for 5G mmWave base stations integrates an 8×8 array antenna, a wafer-level packaged beamformer IC and a frequency converter IC, a bandpass filter that passes only specific frequencies and a combiner/splitter that combines/distributes multiple mmWave signals. In addition, it also integrates a board-to-board (BtoB) connector, a phase locked loop that generates a reference signal for frequency conversion and DC/DC converters that allows the entire board to run on a single 12 V power supply. These features are expected to facilitate the design of 5G mmWave base stations and reduce development costs.
In this demonstration, we will perform "calibration-free beamforming," which does not require phase adjustment (calibration) for beamforming.
Combining this antenna board with a Rohde & Schwarz vector network analyzer (R&S®ZNA67) enables stable phase measurement of frequency conversion devices through real space OTA. By comparing a beam pattern with an unadjusted beam pattern after initial phase adjustment, you can see that the beam direction accuracy is comparable even without adjustment.
On the day, an OTA measurement environment is built using the R&S®ATS800B, a benchtop compact antenna test range (CATR), provided by Rohde & Schwarz.
The CATR can create an indirect far-field environment using a reflector within a compact environment of approximately 1.5 m, thereby reducing the size of the anechoic chamber.
60 GHz mmWave wireless communications module
A video transmission demonstration will be held that combines 60 GHz mmWave wireless communication, which has world-class long-distance transmission capabilities and low latency, with the JPEG XS codec. Participants can experience smooth real-time operation with high-quality, low latency video by playing a simple game while watching the transmitted video and comparing it with video that has delays.
This demonstration will be conducted by combining unlicensed, Fujikura’s low-interference 60 GHz wireless communication links, Extrixa Inc.'s ultra-low latency camera device and into PIX's low latency JPEG XS codec.
