PY - 1995 DA - 1995// TI - Performances of hot—electron superconducting mixer for frequencies less than the gap energy: NbN mixer for 100 GHz operation T2 - Proc. 6[super:th] Int. Symp. Space Terahertz Technol. BT - Proc. 6[super:th] Int. Symp. Space Terahertz Technol. SP - 247 EP - 253 KW - NbN HEB mixers AB - The possibilities to improve the parameters of the 100 GHz NbN HEB superconducting waveguide mixers have been studied. The device consists of a signal strip 1 gm wide by 2 Am long made of 40 A thick NbN film. The best operation point was found at 5 K, where the mixer bandwidth made up 1.5-2 GHz and the total loss diminished down to 8 dB. The critical current density has been increased up to " 40 6 A/cm 2 , the noise temperature of the receiver (DSB) has reduced down to 450 K and the local oscillator power has decreased down to -.4).1 mcV.
