To solve signal-line bandwidth and fan-out problems, microwave sources required for qubit manipulation might be embedded close to the qubit chip, typically operating at temperatures below 4 K. Here, we perform the first low temperature measurements of a 130 nm BiCMOS based SiGe voltage controlled oscillator at cryogenic temperature. We determined the frequency and output power dependence on temperature and magnetic field up to 5 T and measured the temperature influence on its noise performance. The device maintains its full functionality from 300 K to 4 K. The carrier frequency at 4 K increases by 3% with respect to the carrier frequency at 300 K, and the output power at 4 K increases by 10 dB relative to the output power at 300 K. The frequency tuning range of approximately 20% remains unchanged between 300 K and 4 K. In an in-plane magnetic field of 5 T, the carrier frequency shifts by only 0.02% compared to the frequency at zero magnetic field."}],"date_created":"2019-01-10T14:22:23Z","day":"01","publisher":"AIP Publishing","department":[{"_id":"GeKa"}],"isi":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_processing_charge":"No","issue":"11","article_number":"114701","doi":"10.1063/1.5038258","type":"journal_article","oa_version":"Preprint","date_updated":"2024-04-24T22:30:26Z","status":"public","external_id":{"arxiv":["1804.09522"],"isi":["000451735700054"]},"author":[{"first_name":"Arne","last_name":"Hollmann","full_name":"Hollmann, Arne"},{"orcid":"0000-0002-7197-4801","first_name":"Daniel","last_name":"Jirovec","full_name":"Jirovec, Daniel","id":"4C473F58-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Kucharski, Maciej","first_name":"Maciej","last_name":"Kucharski"},{"first_name":"Dietmar","last_name":"Kissinger","full_name":"Kissinger, Dietmar"},{"full_name":"Fischer, Gunter","first_name":"Gunter","last_name":"Fischer"},{"full_name":"Schreiber, Lars R.","first_name":"Lars R.","last_name":"Schreiber"}],"publication_identifier":{"issn":["00346748"]},"month":"11","year":"2018","intvolume":"        89","date_published":"2018-11-01T00:00:00Z","citation":{"chicago":"Hollmann, Arne, Daniel Jirovec, Maciej Kucharski, Dietmar Kissinger, Gunter Fischer, and Lars R.
