Frequency Bands and Channel Architecture
nn
The MOP-TB-727-150P-03NF hybrid combiner operates across three distinct parts, each covering a critical range of modern communication bands. Part 1 handles 698-960 MHz, ideal for LTE and legacy cellular systems. Part 2 spans 1710-1880 MHz, covering PCS and DCS bands. Part 3 addresses 1920-2700 MHz, supporting UMTS, LTE, and emerging 5G mid-band frequencies. This tri-band capability ensures flexibility for multi-operator or multi-standard networks.
nn
Insertion Loss and Return Loss
nn
With an insertion loss of ≤0.3 dB, this combiner minimizes signal degradation, preserving power efficiency across the entire operating range. The return loss or VSWR is maintained at ≤-20 dB (equivalent to a VSWR of 1.22:1), ensuring excellent impedance matching and reducing reflected power. This level of performance is crucial for maintaining signal integrity in high-density urban environments.
nn
Isolation and Power Handling
nn
Isolation between ports reaches ≥50 dB, preventing interference between connected bands or devices. The combiner supports an input power of 300 watts, making it suitable for high-power base stations and repeaters. Additionally, the intermodulation distortion (PIM or IM3) is specified at ≤-155 dBc @ 2×43 dBm, a critical parameter for minimizing noise in sensitive receivers. The device also includes DC/AISG bypass functionality, supporting up to 3000 mA for remote electrical tilt and tower-mounted amplifier control.
nn
Environmental and Mechanical Robustness
nn
Deployments in harsh outdoor conditions demand components that can withstand temperature extremes, moisture, and electrical surges. The MOP-TB-727-150P-03NF is designed for both indoor and outdoor use, carrying an IP67 rating for dust and water ingress protection. It operates reliably from -20°C to +65°C and can be stored in temperatures ranging from -40°C to +85°C. Environmental humidity tolerance spans 5% to 95%, ensuring stable performance in coastal or rainy climates.
nn
Lightning Protection and Surge Handling
nn
One of the standout safety features is the integrated lightning protection. The combiner can handle surges of 10 kA with a 10/350 μs pulse waveform, meeting industry standards for direct lightning strike scenarios. This protection is essential for tower-mounted or exposed installations where electrical storms pose a constant risk.
nn
Mechanical Specifications and Connectors
nn
The compact form factor of 170×140×50 mm (excluding connectors) allows for easy integration into crowded equipment racks or enclosures. The device comes with 4 connectors, available in N-type, 4.3-10, or DIN-Female variants, depending on your specific cabling requirements. The standard grey color ensures low visibility in most installations.
