Sequencers

UHF/VHF Sequencer Unit

The Sequencer is a fully integrated transmission management system purpose-built for UHF and VHF ground station operations. Designed for plug-and-play deployment, the Sequencer simplifies signal routing, amplification, and antenna switching—eliminating the complexity traditionally associated with high-frequency RF setups. Operating on standard 230V AC power with a maximum consumption of 500W, it delivers a compact, reliable, and pre-configured solution for rapid integration into satellite ground systems.

🔧 Core Capabilities

  • Dual-Band Signal Handling: Seamlessly routes and amplifies transmission signals for UHF and VHF bands, ensuring clear and efficient uplinks.
  • High-Power Signal Amplification: Equipped with an integrated High-Power Amplifier (HPA) for clean, robust signal delivery to the antenna.
  • Smart SDR Routing: Accepts input from your Software-Defined Radio (SDR) and dynamically directs transmission to the appropriate band output.
  • Plug-and-Play Architecture: Fully pre-configured at the factory, requiring no user calibration or field setup—reducing time to deployment.

🌐 Key Features

  • Pre-Wired and Pre-Tested: Delivered ready to operate, with all internal connections configured and verified before shipment.
  • Simplified SDR Integration: Connects directly to the Tx output port of your SDR, with dedicated ports for UHF and VHF input/output, enabling seamless RF flow.
  • Optimized Signal Chain: Internal signal routing directs the SDR output to the HPA, then to the designated UHF or VHF output port for antenna transmission.
  • Compact and Reliable Power: Runs on 230V AC, with a low power footprint of ≤500W, suitable for both permanent installations and mobile setups.
