A model is outlined to explain the multifrequency continua of active galactic nucleus (AGN) and QSOs based on synchrotron and Compton emission of secondary electrons. 3C 273 is used as a particular guide for observational constraints since it is so well observed from radio to γ-ray photon energies. In this model the large blue bump and blue bump Compton components arise in the innermost region (R < 1016 cm) near a supermassive compact object with strong magnetic field B ∼ 104 Gauss. Infrared synchrotron emission and infrared Compton components arise in the low-field region (R ∼ 1-10 pc) with B ∼ 10-1 Gauss. The model results in bumps, wiggles, and inflections in the multifrequency continuum that correspond to those observed.
