ACST offers a set of THz sources based on the active multiplication chain approach to provide high power signals beyond 100 GHz. These sources can be use as transmitters for single or multi-pixel applications and the current offer goes up to 360 GHz. ACST sources can be divided in high power and full-band sources. Both kind of sources are based on our special high power multipliers using dedicated Schottky diodes technology. ACST high power sources can provide more than 150 mW and 40 mW power at 150 GHz and 300 GHz, and they offer a bandwidth larger than 25 GHz and 50 GHz respectively. These performances are achieved without any power combining technique placing ACST sources among the most powerful while cheap options in the current THz market. The power handling capabilities of our sources can be increased in a factor of 2 to 4 under customer requirement.
