Why Choose This Product
Designed to anchor high-capacity, multi-operator base stations and heavy-duty Distributed Antenna Systems (DAS), this 698-4000MHz 2×2 Hybrid Coupler provides standard-setting power routing capability. Its ultra-wideband coverage extends up to 4.0GHz, effortlessly combining or splitting legacy cellular frequencies alongside advanced 5G NR mid-band and C-band allocations. Built to withstand demanding macro-cell electrical loads, the unit supports a massive 500W average power rating while maintaining an ultra-clean ≤-160dBc PIM profile to completely eliminate destructive harmonic noise. Protected by a rugged, IP65-rated weatherproof housing and utilizing ultra-reliable 7/16 DIN Female connectors, it ensures high port isolation (≥21dB) and a low VSWR of ≤1.3 in both extreme outdoor environments and indoor telecom facilities.

FAQ
- How does the 698-4000MHz frequency range expand system capabilities?
- While standard hybrid couplers cap out at 2700MHz or 3800MHz, this model extends its operational bandwidth to 4000MHz (4.0GHz). This wideband range ensures absolute coverage for all global sub-6GHz 5G networks, including critical upper C-band segments and private wireless allocations, making it a future-proof investment for infrastructure expansion.
- Why is a 500W average power rating significant for this 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.
- What are the advantages of using DIN Female connectors on this device?
- DIN Female (7/16 DIN) connectors are heavily favored in macro wireless sites because of their massive mechanical strength and large contact surface area. This architecture provides superior power handling, extremely low insertion loss tolerances, and exceptionally stable low-PIM performance under high torque and external wind loads.
- 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 DIN dummy load to guarantee port isolation (≥21dB) and protect the system radios.
- Is this hybrid coupler certified for direct outdoor installation?
- Yes, the unit features an IP65 ingress protection rating and a broad operating temperature range of -35 to +85℃. It is fully prepared for outdoor tower-top, rooftop, and base station shelter environments. For maximum protection against long-term moisture ingress, wrapping the coaxial 7/16 DIN connections with professional weatherproofing mastic tape is recommended.
