DB Broadcast KFG NEXT 1000

The DB Broadcast KFG NEXT 1000  is a high-performance 1000 Watt FM amplifier designed to operate across the full FM radio broadcasting range of 87.5 – 108 MHz. It integrates cutting-edge technologies aimed at enhancing efficiency, reliability, and operational flexibility, making it an ideal choice for professional broadcasting applications.

Key Features:

• Full Frequency Range: Operates across the entire 87.5 – 108 MHz FM band, providing flexibility for various broadcasting needs.
• Compact Design: Housed in a compact 2RU size cabinet (19″ x 2U), offering 0-1050 W output with 0-8 W input, making it suitable for space-constrained environments.

Advanced Technologies:

• GREEN RF™ Technology: Combines advanced 65:1 devices with patented COLD-FET™ technology, delivering:
  • High RF efficiency (>70%)
  • Enhanced safety and reliability
  • Reduced heating and AC power consumption
• Uninterrupted Service: Features an intelligent protection circuit that manages power output without service interruption under various failure conditions (e.g., load mismatching, over-temperature, cooling or module failures).

Cooling Systems:

• Air Cooling: The KFG series is equipped with an oversized air cooling system that limits heat-sink temperature rise to only about 10°C above ambient. It uses externally mounted redundant fans for easy maintenance without operational disruption.
• Optional Liquid Cooling: Available for enhanced thermal management, providing flexibility for different environmental conditions.

Enhanced Durability:

• AAD Technology: Protects against corrosion and environmental degradation with:
  • Anticorodal aluminum components
  • Air ducts that prevent exposure of electronic parts to moisture
  • Tropicalized resin-coated electronic boards and cables for added resistance to salt air.
