MICROLAB's BK-741 is a diplexer which allow combination and separation of the signals in the AWS bands 1695 – 1780 MHz and 2110 – 2180 MHz with the PCS band 1850 – 2000 MHz. To minimize band interreaction, the inputs are well isolated and have minimal insertion loss over their respective frequency bands. The diplexer has been designed using passive, proprietary techniques which minimizes cost and size. At the same time it ensures minimal loss and very high reliability at input powers up to 250 W per input. Mounting brackets are included.
