OUTPUT COMBINATION OF TRANSISTORS IN AN MRT RADIO-FREQUENCY POWER AMPLIFIER

摘要

A power electronic unit for an amplifier of an imaging magnetic resonance tomography (MRT) system is provided. The power electronic unit includes at least one printed circuit board, on which a plurality of transistors are arranged. Ports (e.g., drain and source) of the plurality of transistors are connected together by electrically conductive connections, and the plurality of transistors are all arranged on one side of the at least one printed circuit board. An output line or cable parallel to the connections, at least in sections, runs on the opposing side of the printed circuit board and may be connected or is connected with or without further interconnected elements (e.g., a balun) to transmitting coils of the MRT.
