The NGT-CX-3-2000 3x2kW FM Full Bridge Combiner by Dongguan Newglee is engineered for high-power FM broadcasting systems. It combines three 2kW channels into a unified output with a full bridge architecture, ensuring low insertion loss (≤0.6dB) and robust isolation (≥30dB) between ports. Designed for 87–108MHz operation, it features integrated filtering, a scalable broadband port, and advanced temperature compensation to maintain stability in harsh environments (-10℃ to +55℃). Its compact, silver-plated brass construction minimizes signal degradation, making it ideal for space-constrained broadcast facilities requiring reliable, high-efficiency performance.
Constructed with premium materials including purple copper, silver-plated brass, and aluminum alloy for durability and efficient signal transmission.
Integrated filtering ensures minimal interference and optimized performance across the 87–108MHz frequency range.
Full bridge design with a reserved broadband port for flexible multi-frequency expansion and system scalability.
Exceptional thermal management: ≤12℃ temperature rise under full load and ≤1.5kHz/℃ frequency drift compensation.
High isolation (≥30dB) between narrowband and broadband ports, even at 1MHz frequency intervals.
Compact, low-loss structure with VSWR ≤1.1 and insertion loss ≤0.65dB at ±300kHz offsets.
