Keysight Demonstrates 6G FR3 Characterization Leveraging ADI Technology at MWC 2025

Keysight Technologies teamed up with Analog Devices to demonstrate 6G FR3 radio frequency front-end (RFFE) characterization at Mobile World Congress 2025. The demonstration showcased how to streamline the characterization process, reducing development time and minimizing errors.

FR3 aims to bridge the gap between the extensive coverage of FR1 and the high capacity of FR2, making it a versatile option for future network demands. To validate the design of a new FR3 RFFE Control Interface, development engineers must ensure it is future-proof as the standard evolves. This involves characterizing complex active components to guarantee system performance upon deployment, a process that requires complex test setups, increasing test cycle time and the risk of errors during the development workflow.

Keysight’s PNA-X Network Analyzers simplify the complex characterization test setups with a highly configurable architecture. ADI has successfully developed a comprehensive FR3 radio front-end signal chain (6-18GHz) to accelerate the development of FR3. This accomplishment provides a robust foundation for the seamless integration and deployment of 6G FR3 technology, paving the way for the next generation of wireless communication.
