Epiq Solutions Released Wideband NDR684 Radio
The new radio unit provides 2 GHz of instantaneous bandwidth for complex RF sensing and direction-finding tasks.
Updated on Sept. 22, 2026 in Consumer Electronics
Epiq Solutions has released the NDR684, a wideband software-defined radio designed for intensive RF sensing and survey applications in congested environments. The device is now available for deployment in tasks requiring high-frequency signal processing.
Why it matters
The NDR684 addresses the growing need for high-fidelity signal analysis in crowded spectrums by delivering massive instantaneous bandwidth in a portable form factor. Its architecture enables real-time sensing across wide frequency ranges that are critical for modern communications surveys.
The device features four independent receive channels and supports 500 MHz of instantaneous bandwidth per channel, totaling 2 GHz of system-wide bandwidth. The unit consumes 73 W of power and measures 6.45 x 9.45 x 1.9 inches.
The players
Epiq Solutions
A developer specializing in software-defined radio technology, compact RF modules, and signal processing hardware for industry and defense applications.
AMD Xilinx
A semiconductor provider known for its high-performance field-programmable gate arrays and radio frequency system-on-a-chip architectures used in telecommunications.
The details
The NDR684 utilizes a filter-first super-heterodyne architecture, a design that uses a local oscillator to shift the input signal to a lower intermediate frequency for processing. To ensure accuracy, these channels are factory-calibrated to equalize radio frequency response across varied temperatures. The unit integrates an AMD Xilinx Zynq RFSoC—a system-on-a-chip that combines radio frequency data conversion with programmable logic—to handle signal processing, supporting VITA 49 packet formatting over 100 GbE.

The Tech Race
The NDR684 positions itself at the cutting edge of portable RF sensing by integrating the VITA 49 packet standard with high-throughput 100 GbE output. It competes directly against other wideband radio modules aiming to minimize tuning latency while maximizing signal detection in congested environments.
Professional signal analysts and engineers can use this hardware to improve survey speeds in dense frequency environments. It is currently available for integration into systems that require 12 Vdc power and support for high-speed, 100 GbE-based signal data backhauls.
The takeaway
The NDR684 highlights a shift toward high-bandwidth, portable radio hardware capable of operating up to 18 GHz with microsecond-level tuning. Watch for future performance benchmarks involving its maximum 48 selectable digital down-converters in real-world, congested signal environments.
