SAT-IF Combiner Amplifier

The SAT-IF Combiner Amplifier is a professional-grade signal amplification and combining unit designed for satellite Intermediate Frequency (IF) signal distribution. It merges multiple SAT-IF input signals (typically from multiple LNBs or multiswitch outputs) into a single output while amplifying the signal to compensate for distribution losses in complex MATV or SMATV systems.

Engineered for high performance in large-scale installations such as multi-dwelling units, commercial buildings, or satellite headends, the amplifier operates across the full SAT-IF frequency range (950–2400 MHz) with minimal noise and high output stability. The built-in amplification ensures strong signal levels over long cable runs and multiple distribution points, while maintaining excellent linearity and low distortion.

Key Features:

• Combines & Amplifies SAT-IF Signals – Ideal for headends and multiswitch-based systems.
• Wide Frequency Range – 950–2400 MHz SAT-IF compatibility for universal LNBs and Foxtel systems.
• Integrated Amplification – Maintains signal strength across extended cable runs.
• High Output Levels – Suitable for splitting to multiple receivers or multiswitches.
• Low Noise Performance – Ensures clean, high-quality signal delivery.
• DC Power Pass – Supports powering of LNBs or active components via coaxial cable.
• F-Type Connectors – Reliable and secure signal connection standard.
• Robust Shielded Housing – RF-protected die-cast aluminium body for durability and low interference.
• Compact Form Factor – Fits easily into distribution cabinets or racks.
