ShareLiteTM 1427-1880 / 1920-2690 MHz Diplexer, with Full DC/AISG pass, Single configuration, 4.3-10 Connectors

Rev : B | Rev date : 07 Jan 2022
The Sharelite FDDV Series of diplexers are designed to enable feeder sharing between systems in the 1427-1880 and in the 1920-2690 MHz ranges. 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.
