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. 000861558 536__ $$0G:(DE-HGF)POF3-144$$a144 - Controlling Collective States (POF3-144)$$cPOF3-144$$fPOF III$$x0 000861558 588__ $$aDataset connected to CrossRef 000861558 7001_ $$0P:(DE-HGF)0$$aJirovec, Daniel$$b1 000861558 7001_ $$0P:(DE-HGF)0$$aKucharski, Maciej$$b2 000861558 7001_ $$0P:(DE-HGF)0$$aKissinger, Dietmar$$b3 000861558 7001_ $$0P:(DE-HGF)0$$aFischer, Gunter$$b4 000861558 7001_ $$0P:(DE-Juel1)172641$$aSchreiber, Lars$$b5$$eCorresponding author$$ufzj 000861558 773__ $$0PERI:(DE-600)1472905-2$$a10.1063/1.5038258$$gVol. 89, no. 11, p. 114701 -$$n11$$p114701 -$$tReview of scientific instruments$$v89$$x1089-7623$$y2018 000861558 8564_ $$uhttps://juser.fz-juelich.de/record/861558/files/1.5038258.pdf$$yPublished on 2018-11-13.
