They provide single-ended output at the second harmonic at 38 GHz as well as differential output at 19 GHz. The oscillators show excellent phase noise performance, the fixed-frequency type reaches -95 dBc/Hz at the fundamental frequency and -89 dBc/Hz at the second harmonic, at 100 kHz offset.}, language = {en} } @misc{LemmnitzKuhnertBensetal., author = {Lemmnitz, Christine and Kuhnert, Matthias and Bens, Oliver and G{\"u}nter, A. and Merz, Bruno and H{\"u}ttl, Reinhard F.}, title = {Spatial and temporal variations of actual soil water repellency and their influence on surface runoff}, series = {Hydrological Processes}, volume = {22}, journal = {Hydrological Processes}, number = {12}, issn = {1099-1085}, doi = {10.1002/hyp.6782}, pages = {1976 -- 1984}, language = {en} } @article{LemmnitzKuhnertHaubruck, author = {Lemmnitz, Christine and Kuhnert, Matthias and Haubruck, S.}, title = {Trockenheitsinduzierte Ver{\"a}nderungen hydrologischer Eigenschaften von Oberb{\"o}den eines gest{\"o}rten Standorts in der Bergbaufolgelandschaft}, language = {de} }
