Insight Product Company offers DFM (Deep and Fast Modulated) mm-wave sources at frequencies from 30 to 280 GHz. DFM generators are designed to go swiftly from the generation to the non-generation mode and back.  This process controlled by the external TTL signal. ON/OFF switch time is approximately 2 nanoseconds.

In contrast with the PIN modulators, DFM sources  have no residual signal in the "OFF"  position. These advantage makes them uniquely beneficial for the applications in  the MRI,  EPR, Spectroscopy, Plasma Diognostics, MM-wave Imaging, Radars and Communications.
