C-band is Here!
With the recent conclusion of các C-band (3.7GHz to 3.98GHz) auctions[1] by the FCC in the US, service providers and MNOs will be keen to start monetizing their investment in the spectrum. Thật, new radios which can support the full C-band are already being announced by OEMs[2].
Many of these radios which will also support full Mở RAN interface standards are được built using Xilinx'S MPSoC and RFSoC technology. Bởi bạnsing Xilinx’s Adaptable Digital RF IP OEMs can quickly scale to address these new and demanding radio yêu cầu.
To demonstrate the scalability of the Xilinx silicon and RF IP we have collaborated with Skyworks Inc. to showcase a full C-band 280MHz iBW solution based on Xilinx’s 3rd Generation RFSoC device and the Skyworks SKY66523-11 PA.
Later this year Xilinx will bring the Zynq RFSoC DFE[3] to market. This disruptive technology is a unique combination of programmable logic and custom silicon which will deliver 400MHz of iBW support for a wide range of PA technologies including GaN. The addition of custom silicon will deliver DFE power savings >50% for typical radio use cases. The latest DPD technology will also greatly enhance the PA efficiency delivering an even more significant reduction in the overall radio energy consumption. The good news is that Xilinx’s Digital RF IP will migrate seamlessly to this new platform.
