KRF901150/2 Ericsson Ericsson RBS Radio Frequency Module

The Ericsson KRF901150/2 is a Radio 2203 Core B1 module, a radio frequency unit designed for Ericsson’s mobile network infrastructure. This component serves as part of the radio transmission chain within base station equipment, handling signal processing and transmission functions for cellular network coverage.

The Radio 2203 series is deployed within Ericsson’s RBS (Radio Base Station) portfolio, supporting mobile operators in delivering 2G, 3G, or LTE services depending on the specific configuration. The B1 designation typically refers to the frequency band supported, commonly Band 1 (2100 MHz) used in UMTS/WCDMA deployments across Europe and other regions.

This is a legacy Ericsson radio module from earlier generation base station platforms. While superseded by newer radio unit designs in current network rollouts, these modules remain essential for operators maintaining existing infrastructure or extending the life of deployed base station sites.
