Microlab BK-04 series diplexers enable the combination and separation of signals in the 50 – 220 MHz and 380 – 960 MHz wireless bands. The inputs are isolated and have minimal insertion loss over their respective frequency bands to minimize band inter-reaction. The diplexer is designed using passive, proprietary techniques for low loss, low PIM, and high reliability.

Combine VHF (50-220 MHz) & UHF (380-960 MHz) services
50 dB Input Isolation
50/100 W per port
Guaranteed Low PIM
Minimal RF Insertion Loss
N-type & 4.3-10 Connectors
IP67 Rated
RoHS compliant
