800/1000W C-band BUC Module

This C‑Band 800/1000W satellite BUC supports RF 5.850‑6.425GHz (extendable to 6.725GHz) and IF 950‑1525MHz, with saturated output of 59.5/60.5dBm and typical ‑65dBc in‑band spurious. It accepts 10 MHz external reference, equipped with monitoring and redundancy interfaces for wide‑temperature C‑band satellite ground transmitting stations.

    This C‑Band 800/1000W BUC block up‑converter is developed for C‑band satellite communication ground transmitting systems. Its standard RF frequency covers 5.850‑6.425GHz and can be extended to 6.725GHz. The standard IF ranges 950‑1525MHz with extended IF of 950‑1825MHz. It supports 10 MHz external reference clock, and internal reference is optional. The 800W unit provides 59.5dBm saturated output and 59dBm rated output, while the 1000W version reaches 60.5dBm saturated and 60dBm rated output. It delivers 75 dB small‑signal gain with 55‑75 dB adjustable range in 0.1 dB fine steps. It features ‑25dBc IMD3, in‑band spurious suppression minimum ‑60dBc (typical ‑65dBc) and excellent phase‑noise performance.
    Powered by 200‑240VAC, it adopts WR137‑G grooved waveguide for RF output and N‑female connector for IF input. Management‑and‑control port and redundancy connector are available for device monitoring and system hot‑standby deployment. Measuring 508×425×265 mm and weighing 45 kg, it operates from ‑40℃ to +55℃ under condensing humidity conditions, widely deployed in C‑band satellite ground‑station transmit equipment.
