The NGT-CX-2-1000 2x1kW FM Full Bridge Combiner is a high-performance solution for FM broadcasting systems, operating within 87–108MHz. It combines two 1kW inputs with low insertion loss (≤0.65dB) and high channel isolation (≥30dB), ensuring efficient signal transmission. Built with premium materials and a compact full-bridge structure, it supports seamless expansion via a reserved broadband port. Advanced thermal compensation and a wide operating temperature range (-10°C to +55°C) guarantee reliability in diverse environments. Ideal for broadcasters requiring scalable, low-loss signal combining with robust durability.
High-Quality Materials: Constructed with purple copper, silver-plated brass, and durable aluminum alloy, ensuring superior conductivity and longevity.
Low Loss & High Isolation: Features ≤0.65dB insertion loss, ≤1.09 VSWR, and ≥30dB isolation between channels for minimal signal degradation.
Expandable Design: Full-bridge structure with a reserved broadband port, enabling easy multi-frequency expansion and system scalability.
Robust Thermal Management: Excellent temperature compensation (≤1.5kHz/°C) and ≤12°C full-power temperature rise for stable performance.
Compact & Integrated: Space-saving design with integrated filtering, optimized for high-power FM broadcasting applications.
