ShareLiteTM 380-960/1695-2200/2300-2690 MHz Triplexer, with Full DC/AISG pass, Dual configuration, 4.3-10 Connectors

The Sharelite FTBRM Series of triplexers are designed to enable feeder sharing between systems in the 380-960, 1695-2200 and 2300-2690 MHz range. RFS's innovative cavity filter design provides a very low insertion loss of 0.1-0.15dB 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 reliability. Designed to withstand the most severe outdoor environments, it also features an IP67 class protection 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.
