Microlab BK-3104 is a Triplexer that enables the combining or splitting of PCS/AWS with WCS, 2.5/BRS, or C-Band for 5G carrier aggregation in DAS & small cells in a 2×2 MIMO format. The inputs are well isolated and have minimal insertion loss over their respective frequency bands to minimize band inter-reaction. Attention to mechanical design guarantees low Passive Intermodulation (PIM) for a prolonged period, and the connectors are spaced to be compatible with common protective boots for enhanced weatherproofing, as well as allowing for easy and precise installation with a torque wrench. The units are Dual mounted single diplexers allowing for 2×2 MIMO applications, in both NEX10® and 2.2-5 connectors.
