Die Spektraleigenschaften einer vollständigen Stichprobe radio-selektierter Blazare wurden im gesamten elektromagnetischen Spektrum untersucht. Eigene Messungen im (Sub-)Millimeter Bereich sind dabei durch das Ergebnis einer ausgedehnten Literaturrecherche ergänzt worden. Dabei konnten die ersten Flach-Spektrum Radio-Quasare (FSRQs) mit hohen Synchrotron Peak-Frequenzen entdeckt werden. Die Ergebnisse weisen darauf hin, dass es sich bei den beiden Blazar-Typen, FSRQs und BL Lac Objekte, um zwei verschiedene Typen mit intrinsisch unterschiedlichen Eigenschaften handelt.The spectral properties of a complete sample of radio-selected blazars were analysed in the entire electromagnetic range. Additionally to own observations in the (sub)millimet...
