Product Description

Microlab BK-251E is a diplexer which allows combination and separation of the signals in 1710-1880 MHz and 1920-2200 MHz wireless bands. It allows efficient combining or splitting of the standard cellular bands for use in a base station or distributed antenna system(DAS). To minimize band inter-reaction, the inputs are well isolated and have minimal insertion loss over their respective frequency bands. Attention to mechanical design ensures guaranteed low passive intermodulation. Dual mounted configuration for 2x2 MIMO applications is available as BK-251EW
