Abstract: Examples relate to a concept for a Radio-Frequency (RF) frontend, and for a communication device comprising such an RF frontend. A radio-frequency frontend apparatus comprises a receive branch, comprising circuitry configured to obtain a received signal and a digital pre-distortion feedback signal from an external transceiver device. The radio-frequency frontend apparatus comprises power measurement circuitry configured to generate a first signal that represents a power of the received signal based on the received signal, and to generate a second signal that represents a power of an amplified signal based on the digital pre-distortion feedback signal, the amplified signal being a signal that is amplified by a power amplifier of the external transceiver device.
