DBC0041F2V3

TWIN DIPLEXER 850/900, RACK MOUNTED

Kaelus rack mounted filter assemblies provide the ability to install commonly used filter configurations into a 19inch rack making installation easy and minimising rack space requirements. The DBC0041 provides the following features and benefits:

FEATURES

  • Combines TX/RX of 850 and 900 BTS to one feeder
  • Provides rejection in 900MHz uplink to 850MHz downlink
  • Main and diversity paths
  • Attenuates 850MHz spurious, protecting 900MHz uplink
  • Low passive IM performance
  • 19” rack mounted
