Abstract
The gain bandwidth of a superconducting NbN hot-electron mixer quasioptically coupled to radiation was evaluated in different operation conditions and compared to presently known bolometric mixer models. Heterodyne regime was obtained with a 2.5 THz quantum cascade laser as a local oscillator and alternating thermal loads and also by mixing radiation of the quantum cascade laser and a gas laser. The results rather agree with the hot-spot mixer model than with any of the homogeneous bolometric models.
