MICROLAB's BK-747 is a dual diplexer which allows combination and separation of the signals in the PCS band 1850 – 1995 MHz with the AWS-WCS bands 1695 – 1780 MHz and 2110 – 2360 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 20 W per input. Double unit mounting configurations for quad diplexer applications are available by adding “W“ (stack) or “X“ (side-side) to the part number.
