The NGT-CX-2-50 2x50W FM Full Bridge Combiner is designed for FM broadcasting systems, combining two 50W narrowband signals with high efficiency. Its full bridge structure and integrated filtering ensure low loss (≤0.65dB) and minimal VSWR (≤1.09), while the reserved broadband port supports future frequency expansion. Built with robust materials and advanced temperature compensation, it maintains stability in extreme conditions (-10℃ to +55℃). High isolation (≥30dB) between channels reduces interference, making it ideal for multi-transmitter setups requiring reliable performance and scalability.
Constructed with high-grade materials including purple copper, silver-plated brass, and aluminum alloy for durability and optimal signal transmission.
Integrated filtering and full bridge structure with a reserved broadband port for flexible multi-frequency expansion.
Low insertion loss (≤0.65dB at f0±300kHz) and ultra-low VSWR (≤1.09) ensure efficient power handling.
High isolation (≥30dB between narrowband channels, ≥31dB narrowband-to-broadband) minimizes interference.
Compact design with temperature compensation (≤1.5kHz/℃) and thermal stability (≤12℃ rise under full power).
Operates in harsh environments (-10℃ to +55℃, ≤90% humidity) with a 50W power rating and 87-108MHz frequency range.
