WFC725A - FR3 Extension Board
Designed for researchers, network innovators, and system manufacturers, this compact, plug-and-play board translates RFSoC’s native 10 MHz–7.125 GHz coverage into the emerging FR3 spectrum, enabling rapid prototyping of 5G-Advanced and 6G systems.
Product details
The WFC725A is a high-performance 6G Frequency Range 3 (FR3) radio front-end (RFFE) module, specifically engineered as a frequency extension for Vector Signal Transceivers (VSTs). It supports an extensive frequency range from 6.9 GHz to 25.8 GHz with a massive instantaneous bandwidth (iBW) of up to 1.2 GHz. This board enables seamless up- and down-conversion, making it an essential tool for wideband signal generation and analysis in next-generation wireless infrastructure

The WUPATEC FR3 Extension Board is a high-performance frequency translation solution that bridges the gap between conventional RFSoC coverage (10 MHz–7.125 GHz) and the emerging FR3 spectrum (7.125–24.25 GHz). By upconverting and downconverting RFSoC signals into the FR3 band, it enables the exploration of the full potential of next-generation wireless systems.
Designed for use with the AMD ZCU670 evaluation kit and WUPATEC VST firmware, this compact module delivers up to 1.2 GHz instantaneous bandwidth. It supports sampling rates up to 1.474 GSa/s, making it ideal for multi-carrier, high-order modulation, and MIMO scenarios. Its vector signal generation and analysis capabilities allow precise EVM and ACPR characterization across 7–26 GHz, helping accelerate the design and validation of FR3-ready radio units.
The extension board supports 5G-Advanced—the enhanced version of 5G standardized in 2023, enabling ultra-high-speed data rates, massive capacity, and ultra-low latency—and paves the way for 6G, which will leverage the entire FR3 band to achieve even higher spectral efficiency and support massive simultaneous connections. With the commercialization of 5G-Advanced beginning this year, the FR3 Extension Board provides an indispensable tool for early adopters, academia, and industry leaders shaping the next decade of wireless connectivity.
