Orbital’s Ka-band Block Upconverter (BUC) is engineered for high-speed uplink performance in modern small satellite missions. Optimized for CubeSat and SmallSatapplications this compact, flight-ready unit provides precise frequency translation for high-throughput Software-Defined Radio (SDR) platforms. Supporting software-defined frequency configuration—both pre-launch and in-orbit—this BUC enables adaptive communications and real-time spectrum reallocation. The software-defined approach minimizes onboard hardware constraints while enabling mission extensibility and resilience. Available in both radiation-hardened and COTS space-qualified models, each unit undergoes rigorous RF, mechanical durability, radiation tolerance, and TVAC compliance when specified.
Key Features:
Low phase noise
High linearity
Low amplitude ripple
Enhanced frequency response
Low spurious emissions
Excellent VSWR
Wide frequency coverage across Ka-band
Optimized for 5-year Sun-synchronous LEO missions; customizable for extended or specialized deployments
