The Newglee NGT-CX-3-1000 3x1kW FM Full Bridge Combiner combines three 1kW FM signals into a single output with minimal loss. Designed for broadcast systems, it employs a full-bridge structure with integrated filtering and a reserved broadband port for future expansion. Key specifications include a frequency range of 87–108MHz, ≤0.65dB insertion loss, and ≥30dB isolation between ports. Built with premium materials like silver-plated brass, it ensures reliability in harsh environments (-10℃ to +55℃, ≤90% humidity). Ideal for high-power FM stations requiring scalability and stable performance.
High-Quality Materials: Constructed with purple copper, silver-plated brass, and aluminum alloy for durability and performance.
Low Loss & High Isolation: Features ≤0.65dB insertion loss and ≥30dB isolation between narrowband/broadband ports.
Compact Full-Bridge Design: Integrates three bridge units with a reserved broadband port for expandability.
Temperature Resilience: Excellent compensation ensures ≤12℃ temperature rise under full power and ≤1.5kHz/℃ coefficient.
Broad Compatibility: Operates in 87–108MHz range with adjustable working frequency for user flexibility.
Robust Power Handling: Supports up to 1.2kW input power per channel with VSWR ≤1.1.
