Cavity Coupler Rangeful CC15 15 dB 698–2700 MHz N-Female

The Rangeful CC15 15 dB cavity coupler provides unequal distribution of RF signals with a fixed 15 dB coupling and N-female connector across the 698–2700 MHz band. Designed for network installations and measurement setups, the CC15 attenuates the signal at the side output so that it is 32 times weaker than the main line, enabling controlled division of cellular signals for antennas or devices.

Advantages

The CC15 delivers stable and predictable 15 dB attenuation over a wide frequency range covering GSM, 3G and 4G bands. Its cavity design ensures reliable RF performance for signal monitoring, testing and distribution. The compact mechanical design with an N-female interface makes it easy to integrate into existing coaxial runs and installation topologies.

Suitable for

• Splitting cellular signal between two indoor antennas with different required coverage areas
• Compensating for unequal cable losses when indoor antenna feeders have different lengths
• Network topologies with multiple branches where unequal power division is needed

Key specifications

• Coupling: 15 dB
• Frequency range: 698–2700 MHz
• Connector type: N-female
• Supported standards: GSM, 3G, 4G

How to use

Install the CC15 in the coaxial line between the main feeder and the branch feeders. Orient the main line to the through port and connect the secondary antenna or device to the side output that provides 15 dB attenuation. Ensure proper torque on N-type connectors and use compatible low-loss coaxial cables to maintain expected performance. Verify signal levels after installation and adjust antenna placement as needed.

Usage recommendations

Use the CC15 when you need a stable, fixed attenuation to balance signal levels between areas or to compensate for longer cable runs; avoid using it where equal power split is required or where additional amplification is needed without accounting for the 15 dB loss at the side port.
