- ItemA wideband cryogenic microwave low-noise amplifier(Frankfurt, M. : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2020) Ivanov, Boris I.; Volkhin, Dmitri I.; Novikov, Ilya L.; Pitsun, Dmitri K.; Moskalev, Dmitri O.; Rodionov, Ilya A.; Il'ichev, Evgeni; Vostretsov, Aleksey G.A broadband low-noise four-stage high-electron-mobility transistor amplifier was designed and characterized in a cryogen-free dilution refrigerator at the 3.8 K temperature stage. The obtained power dissipation of the amplifier is below 20 mW. In the frequency range from 6 to 12 GHz its gain exceeds 30 dB. The equivalent noise temperature of the amplifier is below 6 K for the presented frequency range. The amplifier is applicable for any type of cryogenic microwave measurements. As an example we demonstrate here the characterization of the superconducting X-mon qubit coupled to an on-chip coplanar waveguide resonator. ©2020 Ivanov et al.; licensee Beilstein-Institut.License and terms: see end of document.
