Nxbeam has introduced a new integrated software-defined radio, a compact, high-performance X/S/UHF communication system designed to meet the demanding needs of modern satellite missions. Engineered for Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) Earth observation applications, the new radio delivers exceptional throughput in an ultra-small form factor.
At the heart of the system is a high-speed X-band DVB-S2X transmitter operating across the 8.025-8.4 GHz frequency band. Supporting advanced Adaptive Coding and Modulation (ACM) and modulation schemes up to 256-APSK, the transmitter achieves user data rates of up to 1.7 Gbps, with raw data throughput reaching 3.2 Gbps. Full compliance with DVB-S2 and DVB-S2X standards ensures seamless interoperability with most commercial ground station infrastructures.
Complementing the X-band payload, the radio integrates full-duplex S-band and UHF transceivers optimized for telemetry, tracking, and command (TT&C), as well as inter-satellite and satellite-to-ground communications. The S-band transceiver supports up to 10 Mbps data rates for both uplink and downlink, while the UHF transceiver provides robust low-rate links for mission-critical communications.
Despite its capabilities, the integrated radio maintains an exceptionally compact and lightweight design. Measuring just 95 x 95 x 31 mm, well under 0.5U, and weighing only 550 grams, the unit offers one of the highest size-to-performance ratios in its class. Power consumption is optimized for space platforms, with a maximum of 28 W during X-band transmission, alongside lower requirements for S-band and UHF operation.
Designed for the rigors of space, the radio operates across a wide temperature range from -25°C to +65°C, offers radiation tolerance exceeding 15 krad, and is qualified to withstand the shock and vibration profiles associated with SpaceX launches.
