Parallel transmission technology has attracted much attention because of its advantages of uniform excitation and artifact correction in ultra-high field. A 2kW non-magnetic prototype RF amplifier for 5T multi-channel parallel transmission (pTx) is presented. It is equipped with analogic feedback loops and provides a high linearity up to peak output power. It maintains excellent fidelity performance even without a circulator.
