Near infrared photometry and radio observations of a sample of 15 compact flat spectrum radio sources are presented. The sample includes ten QSOs, four BL Lac type objects, and one Seyfert galaxy. The infrared observations were performed with the 3.6 m ESO telescope in four periods in 1980 and 1981; the radio observations at 2 GHz were made with the 13.7 m Itapetinga radiotelescope. Time scales of variability are derived from present data and previous works. The time scales of variability are interpreted in terms of a model in which the variability is only due to synchrotron energy loss and is not related to the size of the source. Some characteristics of the injection mechanism for relativistic electrons are derived.
