Abstract
Models of relativistic jets filled with ultrarelativistic pair plasma have turned out to be very suitable to explain the broadband radiation of $\gamma$-ray blazars. Given the initial injection and cooling of ultrarelativistic pair plasma in an AGN jet has occurred, producing the observed high-energy $\gamma$-ray radiation, we investigate the further evolution of the pair plasma as it continues to move out from the central engine. The effects of thermalization and of the emission of pair bremsstrahlung and annihilation radiation are discussed, and a model for MeV blazars is presented. A model calculation to the special case of PKS~0208-512 is presented.
