Output stage module for a power amplifier device

A power amplifier device comprising:

• an output stage module comprising:
• a housing;
• a carrier arranged within the housing, the carrier being made from a non-electrically-conducting, thermally-conducting material;
• at least two transistor dies arranged on the carrier;
• a first conductor structure in or on the carrier, the first conductor structure connecting drain outputs of the at least two transistor dies to an output signal;
• and
• at least two second conductor structures each conducting an input signal to at least one gate input of the at least two transistor dies,
• wherein at least one transistor die of the at least two transistor dies, in each case, is assigned to a phase of a symmetrical input signal, and
• wherein at least one cooling channel routed adjacent to the at least one transistor die is provided within the carrier.

A magnetic resonance device comprising:

• at least one transmit unit comprising a power amplifier device including:
• an output stage module comprising:
• a housing;
• a carrier arranged within the housing, the carrier being made from a non-electrically-conducting, thermally-conducting material;
• at least two transistor dies arranged on the carrier;
• a first conductor structure in or on the carrier, the first conductor structure connecting drain outputs of the at least two transistor dies to an output signal;
• and
• at least two second conductor structures each conducting an input signal to at least one gate input of the at least two transistor dies,
• wherein at least one transistor die of the at least two transistor dies, in each case, is assigned to a phase of a symmetrical input signal, and
• wherein at least one cooling channel routed adjacent to the at least one transistor die is provided within the carrier.
