A differential power amplifier has at least an input stage and an output stage. A first output stage amplifier is configured to receive a first portion of a differential signal from the input stage at a first output stage input and provide a first amplified signal at a first output stage output. The second output stage amplifier is configured to receive a second portion of the differential signal from the input stage at a second output stage input and provide a second amplified signal at a second output stage output. Power limiter circuitry is connected to the first and/or output stage inputs and is configured to limit a power level of the differential signal prior to being received at the output stage, such that the differential power amplifier and associated filters are not damaged, while the nominal performance of the differential power amplifier at rated power is not significantly affected.
