Abstract
An output stage module for a power amplifier device (e.g., for a power amplifier device of a transmit unit of a magnetic resonance device) includes a housing and a carrier that is arranged within the housing. The carrier is made of a non-electrically-conducting, thermally-conducting material with low electrical losses (e.g., a ceramic carrier). At least two transistor dies are arranged on the carrier. At least one transistor, in each case, is assigned to a phase of a symmetrical input signal. In and/or on the carrier, a first conductor structure connecting (e.g., inductively) a drain output of the at least two transistor dies to an output signal and to second conductor structures each conducting an input signal to at least one gate input of the at least two transistor dies are provided. At least one cooling channel routed adjacent to at least one transistor die of the at least two transistor dies is provided.
