Synopsis

Keywords: RF Arrays & Systems, RF Arrays & Systems, RF power amplifierUltra-high-field magnetic resonance requires higher power capability and transmission efficiency. An 8 kW non-magnetic RF power amplifier with four-way combiner for 5T MRI is presented. The whole module adopts non-magnetization design to improve transmission efficiency, and the power of four MOSFETs is combined by a combiner with adjustable balance to meet the output power of 8 kW.
