The authors report on a terahertz mixing experiment with microbolometers in the resistive state. The authors observed that for a film a mixer gain bandwidth of can be achieved, corresponding to an energy relaxation time of . The experimental results were analyzed using a two-temperature model. As a result, the phonon escape time of was deduced. At the mixer uncorrected noise temperature was . The obtained results show that bolometers are good prospects for the terahertz range as both broadband mixers and fast direct detectors.
