Problem Addressed

Tunable Matching Networks (TMNs) are used widely in radio-frequency applications due to their ability to provide rapid and dynamically-controlled impedance matching. However, to keep up with emergent technology, TMNs need to provide rapid, high-bandwidth, continuous impedance matching over a wide impedance range, need to operate efficiently at high power levels, and need to be integrable with other methods and systems. Phase-Switched TMNs and a novel switching RF amplifier design meet these challenges.
