Main Product Introduction
The 350-2700MHz 50W 4-Way Power Splitter is a foundational component for multi-band wireless distribution. By utilizing a precision-engineered Wilkinson microstrip architecture, this splitter provides high isolation and low VSWR that traditional reactive splitters cannot match at these power levels. Its frequency range is specifically tailored for legacy and 4G infrastructures, enabling a single device to handle public safety communication alongside commercial cellular services. Housed in a durable aluminum alloy enclosure with high-quality N-type connectors, it ensures consistent electrical performance and mechanical reliability for both enterprise DAS and professional lab environments.
Application Scenarios
- Public Safety & TETRA Networks: Distributing critical communication signals in government buildings, tunnels, and airports.
- 4G LTE Indoor DAS: A central distribution point for splitting signal feeds to multiple indoor antennas.
- RF Device Testing: Providing synchronized signal inputs for multi-device testing in R&D and manufacturing.
- Signal Sampling & Monitoring: Extracting precise signal samples from a 50W main line for analysis.

FAQ
- What is the total signal loss per port for this 4-way split?
- The theoretical split loss is 6.0 dB. Including the typical insertion loss of this wideband model, the total measured attenuation per port is approximately 6.5 dB to 7.2 dB depending on the frequency.
- Can I use this for 5G (3.5GHz) applications?
- No. This model is frequency-optimized up to 2700MHz (2.7GHz). For 5G n78 or Wi-Fi 6 applications, please refer to our 600-6000MHz ultra-wideband series.
- Why is “Isolation” important in a Wilkinson splitter?
- Isolation (≥20 dB) ensures that signals reflecting back from one output port (due to an antenna fault, for example) do not affect the other three output ports. This protects the system’s overall stability.
- What should I do with unused output ports?
- MANDATORY: To maintain the 50-ohm impedance and ensure the isolation specs are met, all unused output ports must be terminated with a 50-ohm N-type dummy load.
- Can this model be used outdoors?
- The aluminum housing is rugged, but for permanent outdoor use, it is highly recommended to install it in a weatherproof box or use professional self-amalgamating tape to seal the N-type connector junctions.
