Premium 617-3800MHz 5G Tri-Band Combiner (RF Triplexer)
Streamline your telecom infrastructure and maximize base transceiver station (BTS) capacity with Hefei BRI’s advanced RF passive components. Designed to effortlessly merge low-band, mid-band, and high-band 5G frequencies, this three-band combiner empowers network operators to consolidate multiple signals into one shared antenna pathway.
By eliminating the need to install parallel feeder cables for different network generations, operators can drastically reduce capital expenditures, minimize installation labor, and significantly lower the wind loading on communication towers.
Engineered for Next-Generation 5G Reliability
At Hefei BRI Electronic & Technology Co., Ltd., we understand that whether you are rolling out a sprawling outdoor smart-city network or a highly localized cell site, absolute component reliability is required. Our engineering ensures your hardware meets the highest global standards.
Broad Spectrum Integration: Perfectly combines legacy low bands (617-960MHz), widespread LTE mid bands (1710-2700MHz), and the crucial new 3800MHz 5G bands (3300-3800MHz).
Exceptional Band Isolation: Outstanding port-to-port isolation ensures that all three frequency ranges operate simultaneously without cross-talk or interference.
Ultra-Low PIM Performance: Precisely engineered to maintain perfect signal integrity, preventing passive intermodulation noise from degrading data transmission speeds and overall network capacity.
Heavy-Duty Weatherproofing: Housed in a robust, corrosion-resistant casing, this rf triplexer is fully sealed against harsh elements (IP67), guaranteeing uninterrupted service in extreme climates.
