Superior Electrical Performance for Reliable Operation
The 698-2700/3300-3800MHz dual band combiner with N-female is designed to deliver exceptionally low insertion loss, typically under 0.3 dB. This ensures that signal strength is preserved during combining, directly improving coverage area and data throughput. With return loss less than -20 dB and a VSWR of 1.22, reflections are minimized, maintaining signal purity. The high isolation of greater than 50 dB between ports prevents cross-band interference, a critical factor when running multiple technologies simultaneously.
Robust Build and Environmental Durability
One of the standout features of this combiner is its IP67 protection rating, which guarantees complete protection against dust and temporary immersion in water. It operates reliably across a wide temperature range (-20°C to +65°C) and can be stored in extreme conditions from -40°C to +85°C. The 10 kA lightning protection (10/350 μs pulse) provides an essential safeguard for outdoor installations, reducing the risk of damage from electrical surges. Additionally, the integrated DC/AISG bypass (up to 3000 mA) supports remote electrical tilt (RET) and tower-mounted amplifier (TMA) control without additional cabling.
