The NGT-CX-3-300 3x300W FM Full Bridge Combiner is a high-performance solution for FM broadcast systems requiring efficient signal combining and expansion. Utilizing a full-bridge structure with a reserved broadband port, it supports multi-frequency scalability while maintaining low insertion loss (≤0.6dB) and high isolation (≥30dB). Designed for durability, it integrates premium materials and advanced temperature compensation to ensure stability across -10℃ to +55℃ environments. Ideal for high-power applications up to 350W, its compact design and integrated filtering minimize footprint and simplify deployment in demanding broadcast setups.
High-Quality Materials: Constructed with purple copper, silver-plated brass, and durable aluminum alloy for enhanced conductivity and longevity.
Full-Bridge Design: Features a 3-way combiner with three bridge units and a reserved broadband port for multi-frequency expansion flexibility.
Low Loss & High Isolation: Ensures ≤0.6dB insertion loss, ≤1.1 VSWR, and ≥30dB isolation across narrowband and broadband ports.
Robust Power Handling: Supports up to 350W narrowband input power and 300W operational power within 87–108MHz frequency range.
Temperature Resilience: Includes temperature compensation (≤1.5kHz/℃) and operates reliably in -10℃ to +55℃ environments.
Compact & Integrated: Compact structural design with integrated filtering for reduced footprint and simplified installation.
