Abstract(in English) | We propose a superconducting HEB mixer with an upper heat sink to improve the phonon diffusion efficiency in phonon cooled HEB mixers. First, we designed and fabricated a test-type NbN HEB mixer to investigate the cooling effect of the upper heat sink by measuring IF bandwidths of a mixer with and without heat sink. The SiO films for the upper dielectric heat sink were deposited on the top of the NbN strip. We observed the increase of IF bandwidth by depositing the SiO heat sink. Next, we fabricated actual used NbN HEB mixer with SiO heat sink. As the results of performance measurement, the IF bandwidth was 3.4 GHz, and the receiver noise temperature demonstrated 500 K at 600 GHz band. |
