ShareLiteTM 380-960/1350-1525/1710-1880/1920-2170 MHz Quadplexer
with Full DC/AISG pass, Single configuration, 4.3-10 Connectors

Rev : C | Rev date : 22 Nov 2019
The Sharelite FQBLDW Series of quadplexers is designed to enable feeder sharing among
systems in the 380-960,1350-1525,1710-1880,1920-2170 MHz ranges. RFS' innovative
cavity filter design provides a very low insertion loss of 0.20dB typical while keeping the product extremely compact and lightweight. The use of highly selective filters guarantees a high
isolation level of 50 dB between ports, to ensure an interference-free environment for any
technology deployed. The filter design incorporates lightning protection for additional reliability.
Designed to withstand the most severe outdoor environments, the quadplexer features an IP67
class protection with a vented enclosure to avoid any possible effects of pressure instability,
thus providing a long lasting, extremely reliable solution to any network.


  • Single unit optimizing in-building application
  • Full DC/AISG pass
  • 4.3-10 Connectors - Reduce tower loading with connectors that are 40% smaller and lighter than 7-16 DIN connectors
  • Extremely Low Insertion Loss
  • High level of Rejection between bands - Protection against interference
  • High Power Handling Capability
  • Very compact & small size design - Easy installation and reduced tower load
  • Exceptional reliability & environmental protection (IP-67)
  • Grounding already provided through the mounting bracket
