Satellite communication systems are becoming increasingly sophisticated, requiring flexible RF architectures capable of supporting multiple frequency bands while maintaining high reliability and simplified operation. As earth stations, teleports, broadcast facilities, and VSAT networks continue to evolve, efficient management of Low Noise Block (LNB) converters has become an essential part of maintaining signal quality and operational flexibility.
The Norsat 6-Band Universal LNB Controller (ULC) has been specifically engineered to address this challenge. Designed as a professional microwave control component, the ULC enables seamless switching between six different LNB frequency bands using standard DC voltage and 22 kHz tone commands. Compact, reliable, and easy to integrate, the controller eliminates the complexity of manually switching multi-band LNB systems while ensuring dependable operation in demanding satellite communication environments.
Available from VSATplus, the Norsat Universal LNB Controller is an ideal solution for satellite operators, broadcasters, government organizations, military communications, teleports, and professional VSAT installations requiring intelligent multi-band LNB control.
The Norsat Universal LNB Controller provides intelligent control for satellite systems utilizing multiple LNB frequency bands.
Instead of replacing hardware or manually changing configurations, users can simply select the desired band through voltage and tone commands. The controller automatically routes the appropriate control signals to the connected LNB, providing a simple yet highly reliable switching mechanism.
Its compact industrial enclosure, optional reference signal support, and multiple connector configurations allow the ULC to integrate easily into both new and existing satellite communication systems.
The Norsat 6-Band Universal LNB Controller offers several advanced capabilities designed for professional SATCOM deployments.
One of the major advantages of the Universal LNB Controller is its ability to automatically select among six frequency bands.
Band selection is performed using industry-standard combinations of voltage and 22 kHz tone.
| Selected Band | DC Voltage | 22 kHz Tone |
|---|---|---|
| Band 1 | 13 VDC | Off |
| Band 2 | 13 VDC | On |
| Band 3 | 18 VDC | Off |
| Band 4 | 18 VDC | On |
| Band 5 | 22 VDC | Off |
| Band 6 | 22 VDC | On |
This simple control method makes integration straightforward while maintaining compatibility with professional satellite receiving equipment.
The ULC is available in multiple hardware configurations to suit different installation requirements.
Available options include:
This flexibility allows engineers to configure the controller for nearly any professional satellite installation.
Accurate frequency stability is critical in professional satellite communication systems.
The Universal LNB Controller supports:
An integrated 10 MHz reference provides local frequency stability without requiring external equipment.
Alternatively, an external 10 MHz signal can be injected through the SMA connector for synchronization with external timing systems.
These options make the controller suitable for broadcast, teleport, military, and research applications requiring precise frequency control.
Long cable runs often create voltage drop issues between the controller and the connected LNB.
To overcome this, the ULC includes integrated Line Length Compensation (LLC), providing an additional +1 VDC when required.
This feature helps maintain reliable switching performance across longer cable distances without additional accessories.
Different satellite systems require different connector types.
The Universal LNB Controller is available with:
| Connector | Impedance |
|---|---|
| F Connector | 75 Ω |
| N Connector | 50 Ω |
| SMA Connector | 50 Ω |
This enables compatibility with both broadcast and professional satellite communication infrastructures.
