Kurzfassung
We present recent advances in the development of NbN hot-electron bolometric (HEB) mixers for flying terahertz heterodyne receivers. Three important issues have been addressed: the quality of the source NbN films, effect of the HEB size on the spectral properties of different planar feed antennas and the local oscillator (LO) power required for optimal operation. Studies of NbN films with an atomic force microscope indicated a surface structure that may effect the performance of the smallest mixers. Antenna spectra and noise temperature measured at therahertz frequencies suggest that a frequencies above 2.5 THz the spiral feed provides better overall performance than the twin-slot feed. Direct measurements of the optimal LO power support earlier estimates made in the framework of conventional models.
