MICROLAB's BK-67N WiMAX injector is a filter diplexer. It links WiMAX in the 2490 – 2690 MHz band with a coaxial distributed in-building cellular network or DAS. This gives WiMAX (or LTE-2500) the benefit of the same controlled coverage as the DAS, eliminating many uncertainties. To minimize the effects of the Injector to the DAS the inputs are well isolated and have minimal insertion loss over their respective frequency bands. Corner holes are provided for simple mounting to a surface or cable tray. N standard connectors. Low PIM -140 dBc (2 x +43dBm tones).
