Main Product Introduction
The 670-3800MHz 8-Way Cavity Power Splitter is a high-efficiency distribution hub designed for modern multi-band wireless networks. Unlike standard Wilkinson splitters that rely on lossy PCB substrates, this cavity-style divider utilizes an air-dielectric environment to achieve near-zero internal dielectric loss. This makes it particularly effective for splitting a single high-power 5G or 4G feed into eight balanced outputs with maximum signal integrity. Its Low VSWR characteristics ensure that the base station or repeater sees a stable 50-ohm load, preventing heat buildup and potential damage. Housed in a durable, corrosion-resistant aluminum enclosure with high-quality N-Female connectors, it is engineered for long-term performance in both indoor and outdoor telecommunications environments.
Application Scenarios
- 5G NR & LTE Indoor DAS: Distributing multi-band cellular signals to 8 separate antenna branches in large venues like malls and airports.
- Carrier-Grade Small Cells: Reliable signal splitting for high-density urban 5G deployments where low loss is critical.
- Neutral Host Infrastructure: A universal splitter supporting multiple operators across different frequency bands from 700MHz to 3.5GHz.
- High-Power Base Stations: Durable signal division for macro cell sites requiring weather-resistant and high-power-rated components.

FAQ
- What is the main advantage of an 8-way Cavity Splitter?
- In high-port-count splitters like this 8-way model, cavity designs are far superior to microstrip designs because they offer much lower insertion loss and can handle much higher power without overheating.
- What is the total signal loss per port for this 8-way split?
- The theoretical split loss is 9.0 dB. Due to the high efficiency of the cavity architecture, the actual measured insertion loss is very low (typically ≤0.5 dB), resulting in a total loss per port of approximately 9.5 dB.
- Does this splitter support the 5G n78 (3.5GHz) band?
- Yes, it is fully optimized up to 3800MHz, providing perfect coverage for the global 5G mid-band spectrum (n77/n78).
- Why is “Low VSWR” important for an 8-way splitter?
- With 8 output ports, any mismatch can lead to significant reflected power. Low VSWR ensures that the signal transitions smoothly through the device, maintaining network stability and protecting the power amplifier of the signal source.
- Must I terminate unused ports?
- YES: To maintain the VSWR and system balance, every unused output port must be terminated with a 50-ohm N-type dummy load. For high-power systems, ensure the loads are rated appropriately for the split power level.
