Microlab Model BK-421 is a 3 Channel Multiplexer which allows combination and separation of the signals in the LTE-600, SMR 800 and GSM-850 bands (Channel 1), the 1900 PCS, AWS-1 and AWS-3 bands (Channel 2), and WCS & BRS bands (Channel 3).

To minimize band inter-reaction, the inputs are well isolated and have minimal insertion loss over their respective frequency bands.

The Multiplexer has been designed using passive, proprietary techniques which minimizes PIM effects. It also ensures minimal loss and very high reliability at input powers up to 250W per input port.

This configuration permits DC pass through all ports.
