3-way cavity splitter Rangeful CS3W 50 Ohm 0–3 GHz

The Rangeful CS3W 3-way cavity splitter is a 50 Ω RF power divider designed to provide three equal outputs from a single input across a wide frequency range (0–3 GHz). It is intended for use in cellular amplifier systems and other RF signal distribution applications where even splitting or combining of signal power (up to 50 W) is required. The compact aluminum housing and N-female connectors make it suitable for mounting and connecting coaxial cables in installations with multiple indoor antennas or test and laboratory setups.

Advantages

The CS3W offers low loss splitting with consistent 50 ohm matching, a small and lightweight aluminum enclosure, and high-quality N-female connectors for reliable coaxial connections. Its wideband design supports common mobile bands (800/900/1800/2100/2600 MHz) and other frequencies up to 3 GHz, and the low attenuation allows operation with relatively high input power levels.

Suitable for

• Distribution of mobile signals to three indoor antennas in buildings
• Combining or splitting RF signals in test benches and laboratories
• Communications systems requiring wideband 50 Ω splitting

Key specifications

• Model: Rangeful CS3W
• Impedance: 50 Ω
• Frequency range: 0–3 GHz (includes 800/900/1800/2100/2600 MHz mobile bands)
• Maximum input power: up to 50 W
• Connectors: N-female (input and outputs)
• Housing: aluminum, compact and mountable

How to use

Connect the RF source or amplifier output to the splitter input using an N-male terminated coaxial cable. Attach up to three N-male terminated coaxial cables to the splitter outputs and route them to the indoor antennas or downstream equipment. If fewer than three outputs are used, fit a matched 50 Ω dummy load on each unused port to prevent reflections and maintain proper VSWR. Observe the maximum input power rating and ensure all connectors are tightened to maintain low loss and good impedance matching.

Usage recommendations

Use the CS3W when you need three equal 50 Ω outputs and preserve cable length and connector quality to minimise insertion loss. Verify compatibility with your amplifier or booster (50 Ω systems) and avoid exceed­ing the 50 W input power. For best performance, keep coaxial cable runs short and use high-quality N-type connectors and 50 Ω cables.
