As a recap, to make the choice real easy for you, below is a brief list of all our THz sources. All are based on a reliable IMPATT technology and commercially available now:

             ~ 100 GHz (≥ 80mW)                             ~ 140 GHz (~ 30mW) 
             ~ 100 GHz (~ 200 mW)                          ~ 140 GHz (≥ 90mW) 
             ~ 100 GHz (≥ 400 mW)                          ~ 180 GHz (~ 10mW) 
                        ~ 280 GHz (~ 25mW)          ~ 300 GHz (~ 10mW) 

Most of the models have hybrid equivalents (add on option) implying detachable horn antenna, which allows to use the device both with WR-flange and horn.
