Description
Designed to meet the rigorous standards of modern wireless infrastructure, this combiner utilizes a reactive or hybrid design to ensure low insertion loss and high port-to-port isolation. The housing is typically constructed from high-grade aluminium or brass with a tri-alloy (White Bronze) or silver plating on the connectors to prevent oxidation and maintain superior electrical contact over time.
The -150dBc PIM performance ensures that the noise floor remains exceptionally low, even when multiple high-power carriers are combined. This makes it an ideal choice for neutral-host environments where multiple service providers share the same antenna system. Most models feature N-Female or 4.3-10 connectors and are IP65/IP67 rated, providing weather-resistant durability for both indoor stadium head-ends and sheltered outdoor installations.
Key Technical Advantages
-
Ultra-Low PIM Performance: Rated at -150dBc, it effectively eliminates unwanted signal interference, a “must-have” for maintaining 5G receiver sensitivity.
-
Broadband Frequency Support: Seamlessly covers 698MHz to 2700MHz, including all major sub-3GHz bands used globally for cellular communication.
-
High Isolation: Provides typically ≥20dB to 25dB isolation between input ports, protecting radio sources from cross-talk and feedback.
-
Efficient Power Handling: Built to manage 200W to 300W average power, suitable for high-capacity macro and small-cell sites.
-
Minimal Signal Loss: Engineered for low insertion loss (typically ≤0.2-0.4 dB above split loss), ensuring maximum energy reaches the antennas.
