The NGT-CX-4-1000 4x1kW FM Full Bridge Combiner is engineered for high-efficiency RF signal combining in broadcast systems. It integrates four bridge units with a broadband expansion port, offering flexibility for multi-frequency setups. Featuring silver-plated connectors and advanced thermal management, it ensures stable performance in environments ranging from -10°C to +55°C. With ultra-low insertion loss (≤0.65dB) and high isolation (≥30dB), it minimizes signal degradation while handling up to 1.2kW per channel. Its compact, rugged design suits demanding applications requiring reliable power combining and future scalability. It is suitable for integration into broader fm radio equipment architectures at multi-channel stations.
Constructed with premium materials including purple copper, silver-plated brass, and high-grade aluminum alloy for durability and performance.
Full bridge design with a reserved broadband port enables the fm transmitter combiner to support seamless multi-frequency expansion and system integration.
Low insertion loss (≤0.65dB at f0±300kHz) and high isolation (≥30dB) between narrowband and broadband ports.
Compact structure with integrated filtering, ensuring minimal footprint and optimized signal quality.
Superior temperature compensation (≤1.5kHz/℃) and low thermal rise (≤12℃) under full power operation.
Supports high-power handling up to 1.2kW per channel across 87–108MHz frequency range.
