Premium 1710-1880MHz / 1920-2690MHz Dual Band Combiner
Streamline your base transceiver station (BTS) and drastically reduce tower loading with the high-performance dual band combiner from Hefei BRI Electronic & Technology Co., Ltd. Engineered to multiplex the 1710-1880MHz and 1920-2690MHz frequency bands into a single RF output, this passive component allows operators to share existing feeder cables and antennas without signal degradation.
Whether your network architecture relies on a specialized rf triplexer or standard dual-band integration, our combiners deliver the exceptional port-to-port isolation and ultra-low PIM required for modern cellular communication.
Engineered for Next-Generation Connectivity
As mobile networks expand, minimizing Passive Intermodulation (PIM) and insertion loss is critical. Hefei BRI manufactures RF passive products trusted by telecom leaders worldwide.
Exceptional Isolation: High port-to-port isolation ensures the 1710-1880MHz and 1920-2690MHz bands operate simultaneously without cross-talk or interference.
Ultra-Low PIM: Built to maintain pristine signal integrity, preserving data transmission speeds in dense, high-capacity networks.
Versatile Integration: Seamlessly complements existing BTS infrastructure. While some multi-band expansions may eventually require an rf triplexer, this dual-band solution provides an immediate, cost-effective upgrade for dual-frequency site sharing.
Rugged Durability: Housed in a heavy-duty, weatherproof casing, making it an incredibly reliable solution for both indoor and outdoor deployments.
