A broadband thermal power-measuring detector has been developed for the 300 to 3000 GHz (1 mm to 100 micron) band, with indications that it is useful over a significantly larger frequency interval. Exploratory detector measurements have so far been m

We have carried out an analysls and demonstrated experimentally mixing in the 8-millimeter region using non-linear effects in a bulk semiconductor. In a manner analogous to optical heterodyne mixers, it is not required that the element have instantan
