The NGT-CX-5-300 5x300W FM Full Bridge Combiner by Dongguan Newglee is a high-performance 5-way combiner designed for FM broadcasting (87-108MHz). Featuring a robust full bridge structure with a broadband port, it supports multi-frequency expansion and delivers up to 300W narrowband/500W broadband power handling. With low insertion loss (≤0.6dB), excellent isolation (≥30dB), and temperature stability (≤1.5kHz/℃), it ensures reliable signal integration in diverse environments (-10℃ to +55℃). Its compact, durable build integrates silver-plated brass connectors (7/16" and 1-5/8" SMS ports) and advanced filtering for optimal performance. Ideal for broadcast systems requiring efficient power combining and minimal signal degradation.
Constructed with high-quality materials including purple copper, silver-plated brass, and aluminum alloy for durability and performance.
Full bridge structure with a reserved broadband port, enabling easy multi-frequency expansion and integration.
Low insertion loss (≤0.6dB) and VSWR (≤1.1), ensuring efficient signal transmission and minimal reflection.
High isolation (≥30dB) between narrowband and broadband ports, reducing interference across channels.
Compact design with integrated filtering and temperature compensation (≤1.5kHz/℃) for stable operation in varied environments.
Supports high power input (300W narrowband, 500W broadband) and operates in temperatures from -10℃ to +55℃.
