ABSTRACT:
The apparatus first measures the peak power of a multichannel signal, or representation thereof. The peak power is compared with one or more peak power threshold values. If the measured peak power exceeds a threshold value, the multichannel signal is attenuated prior to being processed by the linear power amplifier.
