As published in the February 2025 edition of Microwave Journal, Nxbeam expands its product portfolio with the introduction of a Multi-Channel Ultra-Broadband Software-Defined Radio (SDR) based on the highly integrated RFSoC-FFE platform. This product is designed for both communication and radar applications, featuring four receivers and four transmitters, providing versatile functionality tailored to various use cases.
For communication applications, the transmitters and receivers can be configured for QAM or DVB-S2X modulations, with adjustable output frequencies reaching up to C-band, based on customer requirements. The ultra-wideband transmitter supports symbol rates of 500 Msps per channel and a raw data rate of up to 4 Gbps per channel. The SDR includes built-in Digital Predistortion (DPD) technology to ensure high linearity.
For radar applications, the transmitter can generate linear chirp waveforms with bandwidths up to 1 GHz, while the receiver functions as both a radar receiver and a data acquisition system. The integrated FPGA offers robust radar signal processing capabilities, making the system suitable for demanding radar applications.
The SDR is packaged in a compact CubeSat form factor and supports high-speed LVDS data transmission as well as 10G-BaseR SFP optical Ethernet connectivity. With low DC power consumption, the system provides an optimal Size, Weight, and Power (SWaP) solution for customers seeking high-performance, energy-efficient systems.
