RF complexity in mobile phones continues to increase rapidly with the advent of 5G, making it more difficult for manufacturers to meet stringent performance requirements. As phones require more antennas and support more frequency bands, it becomes increasingly challenging to maintain antenna performance. Impedance tuners help by maximizing RF power transfer under different conditions and across multiple frequency bands. As a result, they are increasingly being used to optimize performance, reduce design cost and meet 5G requirements.

This white paper describes how impedance tuners can be used and discusses the relative advantages of different impedance tuner designs. It includes several examples of how to achieve significant performance improvements in typical real-world scenarios.
