The Matchstiq™ X40 from Epiq Solutions is a Multi-Channel Software-Defined Radio (SDR) that operates from 1 MHz to 6 GHz (low-frequency configuration) and 1 MHz to 18 GHz (high-frequency configuration). It combines an RF frontend with multiple digital transceiver channels, a high-performance Nvidia Orin NX 16G GPU/CPU, and an AMD Zynq Ultrascale+ FPGA. This SDR supports low and high-frequency configurations with phase-coherent and independent modes and frequency hopping on all RF channels. The low-frequency configuration benefits from reduced SWaP-C and includes four receivers and two transmitters operating over an instantaneous bandwidth of 200 MHz per channel. The high-frequency configuration integrates four receivers and one transmitter and operates over an instantaneous bandwidth of up to 450 MHz per channel. It requires a DC supply and consumes 40-80 W of power.
The Matchstiq X40 has been designed to offer high-performance, digital signal processing functionalities for small form factor applications with challenging SWaP-C requirements. It is ideal for applications that utilize UsX payloads and employ high-performance components to deliver cutting-edge data processing with AI/ML capabilities at the RF edge. This SDR includes clock generator, two RFICs, power status indicators (with LED), memory blocks, RF front-end module (amplifiers, filters, RF block converters, and frequency extension functionality) and serial interfaces. It also supports Libsidekiq API that provides full control and development of SDR on Linux OS via serial USB, GbE, and GPIO interfaces.
The Matchstiq X40 delivers an output power of 0 dBm on the Tx side and has a noise figure of less than 12 dB on the Rx side (low and high-frequency variants). It uses a sampling bit size of 16 bits (ADC) and 14 bits (DAC) on both the Tx and Rx chains. This SDR is available in an enclosure that measures 4.25 x 8.5 x 1.45 inches and is ideal for direction finding, signal analysis, and network management applications.
