Product Overview
The Dual Band Combiner (Diplexer) is a high-performance solution designed to integrate the 698-960MHz and 1710-2700MHz frequency bands into a single output. This single-unit modular device is equipped with the latest 4.3-10 female connectors, offering superior PIM performance (≤-155dBc) and lower weight for modern network deployments. With its robust IP65 waterproof rating, it is perfectly suited for both pole and wall mounting in demanding indoor and outdoor environments.

Frequently Asked Questions
- Q1: What is the benefit of the 4.3-10 connector on this diplexer?
- A: The 4.3-10 connector is designed for the modern wireless market. It is smaller and lighter than traditional 7/16 DIN connectors while providing much more stable PIM performance and better impedance matching, which is crucial for high-capacity LTE and 5G networks.
- Q2: Why is the ≥22dB return loss important?
- A: A high Return Loss (≥22dB) indicates excellent impedance matching at all ports. This minimizes signal reflection back to the transmitter, protecting sensitive equipment and ensuring maximum power is delivered to the antenna.
- Q3: Can this device power an active antenna or TMA?
- A: Yes. The diplexer features DC Pass (up to 3A) on both ports, allowing you to send power and AISG control signals from the base station to tower-top electronics through the RF path.
- Q4: How does the isolation rating impact dual-band performance?
- A: With an isolation of ≥50dB, the device ensures that signals from the 698-960MHz band do not leak into the 1710-2700MHz path (and vice versa). This high separation prevents cross-interference and maintains signal purity.
- Q5: Is this diplexer durable enough for coastal or high-humidity areas?
- A: Absolutely. It is rated IP65 for waterproof protection and can operate in humidity up to 95%. The customized grey coating also provides excellent resistance to environmental corrosion.
