The NGT-CX-4-2000 4x2kW FM Full Bridge Combiner integrates advanced full-bridge architecture and premium materials to deliver high-power FM signal combining with minimal loss. Designed for broadcast systems requiring scalability, it features a reserved broadband port for seamless multi-frequency expansion and ensures ≤1.1 VSWR across narrowband and broadband channels. Its compact, temperature-stabilized design operates reliably in harsh conditions (-10℃ to +55℃), while integrated filtering and ≥30dB isolation enhance signal clarity. Ideal for high-power FM stations, this combiner combines robust performance with future-ready flexibility.
Constructed with premium materials including purple copper, silver-plated brass, and high-quality aluminum alloy for durability and efficient signal transmission.
Full bridge design with integrated filtering and reserved broadband port, enabling easy multi-frequency expansion and stable performance.
Low insertion loss (≤0.6dB per unit) and high isolation (≥30dB between narrowband and broadband channels) for minimal signal degradation.
Compact structural design with excellent temperature compensation (≤1.5kHz/℃) and low power temperature rise (≤12℃), ensuring reliability in varied environments.
Supports 2kW narrowband input power and operates across 87–108MHz, adaptable to user-defined working frequencies.
Robust environmental tolerance (-10℃ to +55℃, ≤90% humidity, 86–106kPa pressure) for versatile deployment.
