Microlab Model BK-81N series Wireless Local Area Network (W-LAN) Injector is a filter diplexer based on BK-21N. This model has been designed and tested to meet the European Rail Standards. The Diplexer links W-LAN designed to 802.11(b) or (g) with a coaxial DAS, a distributed antenna system.
To minimize the effects of the WLAN Injector to the DAS, the inputs are well isolated and have minimal insertion loss over their respective frequency bands.
The W-LAN Injector has been designed using passive, proprietary techniques to ensure minimal loss and very high reliability. Corner holes are provided for simple mounting to a surface or cable tray. Unit is also available with 7-16 mm DIN connectors as the BK-81D.
