Cavity Coupler Rangeful CC5 698–2700 MHz N Female — 5 dB

The Rangeful CC5 5 dB cavity coupler is an RF device for unequal distribution of cellular and wireless signals. It provides a fixed 5 dB coupling to the side port, which results in the side output receiving approximately 68% less power than the main line. The CC5 covers a broad frequency range of 698–2700 MHz and is compatible with common GSM, 3G and 4G mobile standards. The N‑female connector and compact cavity design make the coupler suitable for integration into signal distribution chains, test setups and base station monitoring.

Advantages

The cavity coupler delivers a stable, broadband 5 dB coupling level across 698–2700 MHz, enabling predictable signal division between main and side outputs. Its N‑female connector simplifies connection to standard coaxial cables and equipment. Using a fixed directional coupler avoids active amplification and provides passive, low-maintenance signal routing suitable for both infrastructure and laboratory use.

Suitable for

• Splitting signal between two indoor antennas with different coverage requirements
• Compensating for unequal cable losses by providing higher power to longer cable runs
• Signal sampling, monitoring or routing in cellular infrastructure and test setups
• Non-amplified distribution where passive, fixed coupling is required

How to use

Install the CC5 between the incoming feed line and the antenna branches: connect the main line to the main port and the branch antennas or devices to the main and side outputs respectively, using compatible N‑connector coaxial cables. Ensure correct cable routing and secure connections. Because the side port is attenuated by 5 dB, orient the side output to the antenna or cable serving the smaller coverage area or the cable run that requires compensation for loss.

Usage recommendations

Use the CC5 when passive, predictable division of RF energy is needed without amplification. For long cable runs, measure the total insertion loss and choose cable types and antenna placement accordingly; pair the coupler with appropriate connectors and grounding practices to maintain signal integrity.
