Datasheet MA12040 (Infineon) - 10

Note 1:
The thermal design of the target application will significantly impact the ability to achieve the peak output power levels for extended time. See “Thermal Characteristics and Test Signals” section for thermal optimization recommendations.
Note 2:
Continuous power measurements were performed on the MA12040/MA12040P proprietary Amplifier EVK without heatsinking at 25⁰C ambient temperature in Power Mode Profile 4.
Note 3:
Power MOSFET switching frequency depends on which properties are assigned to the individual power modes of the device. Detailed information on this can be found in “Power Mode Management” section.
