Outline Drawing

Four Bands, One Clean Output

A combiner should merge signals without creating interference between bands. This RF 4 Way Combiner accepts four inputs — GSM uplink (880-915MHz), GSM downlink (925-960MHz), DCS uplink (1715-1790MHz), and DCS downlink (1805-1880MHz) — and delivers a single combined output. The RF 4 Way Combiner maintains ≤2dB insertion loss across all four passbands, so your signal strength stays intact. VSWR is ≤1.5:1, minimizing reflections that could disrupt your base station or repeater.

Isolation That Prevents Cross-Talk

What makes this RF 4 Way Combiner truly effective is its port-to-port isolation. Each input sees ≥80dB rejection from signals in the other three bands. That means GSM uplink noise won’t leak into your DCS downlink path — no desensitization, no dropped calls. The RF 4 Way Combiner handles 100W continuous power and operates at 50Ω impedance. The aluminum housing with black paint finish and SMA-Female connectors ensures reliable performance in telecom shelters and outdoor cabinets.
