Why Choose This Product
The 819-3900MHz Multi-Band 2×2 Hybrid Coupler is built to meet the rigorous demands of high-capacity neutral-host DAS and multi-operator base stations. Operating across discrete cellular allocations up to 3.9GHz, it seamlessly routes legacy low-band, mid-band LTE, and 5G NR sub-6GHz (including n78 C-band) signals. The unit features distinct Long-Neck N-Female connectors, elongated to facilitate effortless tool clearance and rapid weatherproofing tape application during field installs. With a robust 500W per port power rating and an ultra-low PIM profile of ≤-155dBc, it maintains a clean noise floor under heavy macro-cell loads. Housed in an advanced IP67-sealed enclosure, it guarantees flawless electrical performance and high port isolation (≥22dB) in extreme indoor and outdoor installations.

FAQ
- What are the primary benefits of the “Long-Neck” connector design?
- The Long-Neck N-Female connectors feature an elongated neck design that extends the interface away from the coupler chassis. This provides valuable mechanical clearance, making it significantly easier for technicians to use torque wrenches during installation and allowing for a tighter, more secure wrap of self-amalgamating weatherproofing tape in the field.
- How does the segmented frequency response support modern networks?
- This coupler is optimized for multi-band wireless systems by covering major standard operational bands: 819-960MHz, 1710-1870MHz, 1885-2170MHz, 2300-2700MHz, and 3350-3900MHz. This comprehensive filtering and coupling path ensures absolute compatibility with global GSM, UMTS, 4G LTE, and mid-band 5G NR deployments.
- Why is a 500W per port capacity important for this hybrid coupler?
- A 500W average power handling rating indicates macro-cell base station caliber engineering. It allows the coupler to safely process high-amplitude, multi-carrier, and multi-operator transmissions concurrently without the risk of thermal breakdown, signal clipping, or internal microstrip degradation.
- How should the 2×2 port configuration be utilized for signal combining?
- In a 2×2 combining application, two separate input signals (e.g., from different base stations) are routed into the two input ports. The internal 3dB matrix blends the signals and splits the combined power equally across the two output ports with a 90-degree phase shift. If only one antenna path is deployed, the remaining unused output port must be terminated with a high-power 50Ω dummy load to guarantee port isolation (≥22dB) and protect the system radios.
- What environmental protection does the IP67 rating offer?
- An IP67 ingress protection rating indicates premium environmental engineering. The unit is completely dust-tight and can withstand temporary immersion in water up to 1 meter deep. This makes it highly dependable for harsh, unshielded outdoor environments such as rooftop antenna positions and tower tops, as well as indoor setups.
