Product Description

Microlab BK-311EW is a Dual triplexer which allows combination and separation of the signals in 698-960 MHz, 1710-1880 MHz and 1920-2170 MHz wireless bands. 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. The Triplexer has been designed using passive, proprietary techniques which minimizes cost and size. It allows efficient combining or division of the standard cellular bands for use in a base station, coaxial distributed in-building cellular network or DAS.
