ROFU1310020/2 Ericsson Ericsson RBS Radio Frequency Module

The Ericsson ROFU1310020/2 is an LFU7 (Low-loss Filter Unit) designed for use in Ericsson Radio Base Station (RBS) infrastructure. This radio frequency filter unit provides essential signal filtering and combining functions within the RF chain, helping to maintain signal integrity and minimise interference in mobile network deployments.

The LFU7 is typically deployed as part of Ericsson’s macro base station equipment, where it sits between the radio units and antenna systems. It plays a critical role in frequency management, allowing efficient transmission and reception across designated frequency bands while rejecting out-of-band signals.

This is a legacy component from Ericsson’s earlier RBS portfolio. While superseded by newer radio architectures, the LFU7 remains essential for operators maintaining and extending the service life of existing 2G/3G infrastructure or requiring spares for deployed networks.
