A device for radio-frequency power amplification having a switching arrangement is provided. The switching arrangement is configured to amplify, during operation, a radio-frequency input signal that is present at a signal input and has a low input power, and to provide, during continuous wave (CW) operation, a continuous output signal at an output. The switching arrangement includes at least two amplifier devices. A respective output of the at least two amplifier devices is connected to the output of the switching arrangement. Each of the amplifier devices includes at least one switching transistor. The switching transistors are not operable during CW operation without being destroyed. The at least two amplifier devices are drivable as pulse amplifiers with a temporal offset by a control device such that the pulses generated in temporal succession at the outputs of the at least two amplifier devices produce a CW signal at the output. |

1. A device for radio-frequency power amplification, the device comprising:
a switching arrangement with a signal input and a signal output, the switching arrangement being configured to amplify, during operation, a radio-frequency input signal that is present at the signal input and has a low input power, and to provide, during continuous wave (CW) operation, a continuous output signal at the output, the continuous output signal having a greater output power compared with the input power, wherein the switching arrangement comprises at least two amplifier devices, a respective output of the at least two amplifier devices being connected to the output of the switching arrangement, wherein each of the at least two amplifier devices comprises a switching transistor, wherein the switching transistors are configured to be inoperable during CW operation without being destroyed, and wherein the at least two amplifier devices are drivable as pulse amplifiers with a temporal offset using a control device such that the pulses generated in temporal succession at the outputs of the at least two amplifier devices produce a CW signal at the output. |
