Abstract: According to the current understanding of the electromagnetic radiation of blazars, the broadband spectrum of a blazar consists of two general components:(a) a low-energy component which is believed to be the result of synchrotron radiation of a beam of relativistic particles and which peaks, in the spectral energy distribution (SED), in the IR to soft X-ray region; (b) a high-energy component which is likely the result of inverse Compton scattering of the same beam of relativistic particles on some ambient field of soft photons and which peaks in the GeV/TeV region. The positions of these two peaks in SED are thus closely related to each other and are also related to other basic properties of the radiating blazar. This general picture will be examined here in the light of EGRET-detected blazars.
