Signal Generator Extension Modules



Virginia Diodes, Inc. (VDI) Signal Generator Extension (SGX) modules provide high performance frequency extension of microwave signal generators into the THz range. VDI SGX modules offer full waveguide band coverage and are available from WR15 (50 to 75 GHz) to WM-164 (1.1 to 1.5 THz) with additional bands under development. This turn-key, sweepable solution is compatible with any microwave signal generator that meets the input frequency and power requirements.

Certain modules can be configured with rapidly interchangeable components for extended frequency coverage. Click here to contact VDI for more information.
