ShareLiteTM 555-806/824-960 MHz Twin Diplexer with Auto DC/AISG Sense, Dual configuration, 4.3-10 Connectors

Rev : B | Rev date : 07 Sep 2018
The FDJ8 Series of diplexers are designed to enable feeder sharing between systems in the 555-806 MHz range and in the 824-960 MHz range. RFS's innovative cavity filter design provides a very low insertion loss of 0.2dB typical while keeping the product extremely compact and lightweight. The usage of highly selective filters also guarantees a high isolation level of 50dB between ports, to ensure an interference-free environment for any technology deployed. The filter design also comprises of lightning protection for additional reliabiltiy. Designed to withstand the most severe outdoor environments, it also features an IP67 class pretection with a vented enclosure to avoid any possible effects of condensation and pressure instability, thus providing a long lasting, extremely reliable solution to any network.


  • Dual unit for use with X-pol Antennas
  • Auto DC sense to prevent installation mistakes and eliminate the need for DC stops
  • Extremely Low Insertion Loss
  • High level of Rejection between bands - Protection against interference
  • Extremely High Power Handling Capability
  • 4.3-10 connectors - Reduce tower loading with connectors that are 40% smaller and lighter than 7/16 DIN connectors
  • Very compact & small size design - Easy installation and reduced tower load
  • Exceptional reliability & environmental protection (IP-67)
  • Mounting hardware for Wall and Pole mount provided (P/N SEM2-1A)
  • Grounding already provided through the mounting bracket
