474390A.101 Nokia Nokia Base Station Radio Frequency Module

The Nokia 474390A.101 is a Bias-T module designed to inject DC power onto an RF coaxial line while maintaining signal integrity. Bias-T devices are essential components in telecommunications and radio frequency systems, allowing power and RF signals to share a single coaxial cable without interference between the two.

This component is typically deployed in Nokia mobile network infrastructure, where it enables remote powering of active RF components such as tower-mounted amplifiers, remote radio heads, or other antenna-line devices. By combining DC and RF paths, Bias-T modules reduce cable runs and simplify installation in base station environments.

As a Nokia telecommunications infrastructure component, the 474390A.101 is designed for integration into mobile network equipment. This part may be associated with legacy or specific-generation Nokia base station platforms and is suited for maintenance, repair, or expansion of existing network deployments.
