15dB DIRECTIONAL COUPLER N F/F 700-3500MHz

Description

Engineered for modern telecommunications infrastructure, this coupler supports a seamless frequency spectrum that covers both legacy cellular bands and the latest 5G mid-band allocations. The internal circuitry is typically housed in a high-grade brass or aluminum casing with tri-alloy plating to ensure excellent conductivity and long-term resistance to environmental corrosion.

The N-Female connectors are precision-machined for secure, low-loss connections that can withstand high installation torque. This coupler is frequently utilized in Distributed Antenna Systems (DAS) and in-building solutions (IBS) to sample signal levels for monitoring equipment or to provide a low-power signal feed for a secondary coverage area. Its high isolation rating (typically ≥26dB) ensures that signals remain distinct, preventing interference between the input and coupled ports.

Key Technical Advantages

• Broadband Versatility: Covers the expanded 700MHz to 3500MHz spectrum, ensuring compatibility with global 4G and 5G network standards.

• Minimal Mainline Insertion Loss: With a 15dB coupling factor, the mainline insertion loss is kept very low (typically ≤1.25 dB), maximizing the reach of the primary signal.

• High Power Performance: Capable of handling up to 300W average power, making it suitable for use at the output of high-power base station amplifiers.

• Signal Integrity: Optimized for low PIM (Passive Intermodulation) to maintain a clean noise floor, which is critical for maximizing 5G data throughput.

• Industrial Durability: Features a rugged metal build with an operating temperature range from -25°C to +70°C, suitable for various climate conditions.
