Broadcast amplifier pallets offer a low-cost solution in creating MR compatible non-magnetic transmit array systems capable of operating in both 1.5T and 3T B0 fields. We developed a locally deployable PTx array utilizing readily available broadcast amplifier pallets. The conversion of a conventional slow-gated, non-linear FM band (88-108MHz) 1kW pallet to a fast-gated, linear non-magnetic amplifier targeting transmit array deployment in both 1.5T and 3T B0 fields is demonstrated.
