KRF102452/2 Ericsson Ericsson RBS Radio Frequency Module

The Ericsson KRF102452/2 is a diplex filter designed for operation in the 1900 MHz frequency band. Diplex filters are passive RF components that enable the separation or combination of two different frequency bands on a single antenna feed, allowing simultaneous transmission and reception without interference between the uplink and downlink paths.

This filter is intended for use within Ericsson radio base station infrastructure, typically deployed in mobile network environments operating PCS 1900 or similar frequency allocations. It forms part of the antenna system, sitting between the radio units and the antenna to manage signal routing efficiently.

The KRF102452/2 is a legacy component from Ericsson’s earlier generations of mobile network equipment. It remains relevant for operators maintaining or extending existing 2G/3G networks that utilise the 1900 MHz spectrum, particularly in markets where this band is allocated for GSM or UMTS services.
