ShareLiteTM 380-960/1427-1880/1920-2200/2300-2690 MHz Quadplexer with Full DC/AISG pass, Dual configuration, 4.3-10 Connectors

Rev : C | Rev date : 27 Jun 2018
The Sharelite FQBDWM Series of quadplexers is designed to enable feeder sharing among systems in the 380-960, 1427-1880, 1920-2200, and 2300-2690 MHz ranges.  RFS' innovative cavity filter design provides a very low insertion loss of 0.3dB 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.
