Parallel transmission in MRI has created a need for multiple, independently controlled power amplifier channels. Meeting this need with multiple, intermediate powered amplifiers opens the possibility to move the amplifiers closer to the RF coil to eliminate cable losses. Eight 1 kW A/B linear RF Amplifiers operating inside a 7T magnet bore are demonstrated.
