UHF (Ultra high field) MRI requires high RF power from RF Power Amplifier (RFPA), especially for whole-body imaging1. Some studies on body imaging reported limitation on available RF power. In this study, we present works to provide RFPA with highest peak power capability known for UHF MRI with configurable number of transmit channels so as to meet different RF coil requirements. Feasibility and performance of the new method in UHF MRI was demonstrated on the bench and 5T whole-body scanner.
