Technical Advantages

• Multi-Band RF Infrastructure Integration

The Quad Band Combiner enables four frequency bands to share a common antenna system, reducing passive infrastructure requirements and simplifying DAS deployment.

• Ultra-Low Signal Loss

With insertion loss ≤0.3dB, the product minimizes RF attenuation and maintains high-quality wireless signal transmission.

• Excellent RF Isolation

≥50dB isolation between ports prevents unwanted interference between different frequency bands and improves system stability.

• Low PIM Performance for High Capacity Networks

The ≤-150dBc passive intermodulation performance reduces unwanted RF interference generated by multiple carriers, supporting high-capacity LTE and 5G networks.

• AISG Transparent Design

The AISG/DC bypass function allows antenna control signals and DC power to pass through the combiner for remote antenna system applications.
