BK-251E Image

The BK-251E from Microlab is a Diplexer which allows combination and separation of the signals in 1710 - 1880 MHz (Port 1) and 1920 - 2200 MHz (Port 2) frequency bands. It combines DCS and IMT bands for Distributed Antenna System (DAS) applications. To minimize band inter-reaction, the inputs are well isolated and have minimal insertion loss over their respective frequency bands. It can handle up to 200 W of input power at each port, has an insertion loss of less than 0.35 dB, and provides isolation of over 50 dB. This diplexer has a PIM of -155 dBc and allows efficient combining or splitting of the standard cellular bands for use in a base station or DAS.

The BK-251E is available in an IP67-rated module that measures 201 x 164 x 52 mm with 4.3 - 10 (F) connectors. It is also available in a dual-mounted configuration for 2x2 MIMO applications.
