Description
Engineered for reliable network integration, this combiner features a high-grade aluminum or brass housing with tri-alloy (White Bronze) plating on the connectors. This finish ensures excellent conductivity and protects against environmental oxidation. The internal circuit is designed to provide high isolation between the two input ports (typically ≥ 20dB), preventing feedback and ensuring that each signal source remains stable.
The -130dBc PIM performance is achieved through precision internal machining and the use of non-magnetic components. While slightly higher than premium “ultra-low PIM” models, this rating is effective for many commercial and private LTE/5G applications. The device usually comes with N-Female or 4.3-10 connectors and is often IP65 rated for durability in both indoor and sheltered outdoor environments.
Key Technical Advantages
-
Seamless Frequency Integration: Covers all major cellular bands from 698MHz to 2700MHz, allowing for the combination of different carriers or technologies (e.g., GSM + LTE).
-
High Port Isolation: Maintains a minimum of 20dB isolation between input ports, protecting sensitive radio equipment from cross-interference.
-
Low Insertion Loss: Engineered to minimize signal attenuation (typically ≤ 0.4dB plus the theoretical 3dB split loss), maximizing the radiated power at the antenna.
-
Compact and Robust: Designed with a small footprint for easy mounting in congested head-end racks or wall-mount enclosures.
-
Standard PIM Protection: The -130dBc rating provides sufficient signal cleanliness for many medium-capacity network installations.
