Insight Product Company offers synthesizers at frequencies from 30 to 280 GHz which can be used in EPR/ ESR experiments. These sythnesizers are designed to go swiftly from the generation to the non-generation mode and back.  This process is controlled by external TTL signal. There is also the possibility to manipulate the phase, namely to shift it by 90 degrees and 180 degrees. ON/OFF switch time is approximately 2 nanoseconds. The synthesizer enables high frequency stability by phase-locking to a low frequency source.

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