SKDMA13*13 - Amplifier

Core Specifications

• Inputs: 13 total – 12 SAT-IF signals (from three Quattro LNBs, supporting 3 satellite positions × 4 bands/polarities) + 1 terrestrial (VHF/UHF) input 

• Outputs: 13 amplified outputs ideal for feeding matching 13×13 distribution or cascading into larger setups

⚙️ Signal Amplification & Control

• Amplification:

  • Satellite gain ≈ 30 dB

  • Terrestrial gain ≈ 27 dB

• Adjustability: Gain and slope can be fine-tuned to balance signal levels across multiple outputs 

• Return Channel: Supports passive return (5–65 MHz), preserving interactivity for receivers 

📐 Technical Performance

• Frequency Ranges:

  • Satellite IF: 950–2400 MHz

  • Terrestrial: approx. 88–862 MHz 

• Output Levels:

  • SAT up to ~119 dBµV

  • TERR up to ~112 dBµV 

• Isolation: ≥ 30 dB between various signal paths; high shielding via zamak housing 

🔌 Power & Installation

• Power Supply: Operates on 12 V DC, typically sourced from included PSU — consumption max ~865 mA at 12 V 

• Build: Compact zamak metal casing (~280×121×30 mm, 0.73 kg) designed for indoor rack or cabinet installation 

✅ Ideal Applications

• Designed for medium to large-scale SMATV systems, especially supporting up to 13 clients

• Facilitates cascading distribution, enabling further expansion via additional multiswitches

• Ideal for residential complexes, hotels, or campus buildings with high-end satellite + terrestrial TV needs
