MICROLAB's BK-745 is a dual diplexer which allows combination and separation of the signals in the PCS band 1850 – 1990 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 100 W per input. Double unit mounting configuration for quad diplexer applications is available as Microlab model BK-745EW.
