Development of high-sensitivity, wide-IF band heterodyne receiver in THz frequency range

(National Institute of Information and Communications Technology (NICT)) The National Institute of Information and Communications Technology has developed a unique superconducting hot electron bolometer mixer (HEBM) using magnetic materials. The 2 THz band HEBM produced this time has a low noise performance of about 570 K (DSB), which is about 6 times the quantum noise limit, and a wide IF band characteristic of about 6.9 GHz, which is about 3 GHz larger than the conventional structure HEBM.
