The global and observed parameters of 33 extragalactic sources with radio jets and superluminal motions are derived and compared to study the relationship between the kinematic and radiative properties of the jets. The sample of AGNs includes 22 quasars, 6 blazars, 3 radiogalaxies, an empty-field radio source, and a Seyfert galaxy. The magnetic field, maximum brightness temperature Tb, source luminosity, and the characteristic frequency of the synchrotron emission are evaluated for each object by applying observed parameters to a model prediction of jets. The relativistic model luminosities are found to be correlated in the same manner as the observed luminosities, and Tb values range from 10 exp 11 to 10 exp 13 K. It is suggested that specific types of jets exist for high- vs low-luminosity sources, and a relation is proposed between emission mechanisms and observed FIR and X-ray emission.
