📡 Nokia RRU FZFF-e – High-Power 6T6R 1800 MHz Remote Radio Unit

Product Overview

The Nokia RRU FZFF-e (Part No. 472834A) is a 6-transmit, 6-receive (6T6R) outdoor Flexi RF Module used for LTE FDD Band 3 (1800 MHz) and GSM 1800 macro-cell deployments.
It delivers up to 6 × 60 W (360 W total) RF output power and is engineered for multi-technology support—LTE, GSM, and WCDMA—within one compact, IP-rated enclosure.
The FZFF-e succeeds earlier FXED modules, providing improved energy efficiency and a smaller footprint while retaining backward compatibility with Flexi System Modules and AirScale Basebands.
