A compact high power RF driver module is available in output powers of 50 or 100W. Powered from 28vDC,
the modulation inputs allow either full digital control or activation of an internal pulse generator.
First pulse suppression is implemented through either analogue modulation, RF off analogue control,
triggered first pulse suppression, or triggered pre-pulse kill, as described in our FPS guidance notes.
On board LED's and TTL logic outputs monitor driver status and cooling is through forced air over the
heat sink.
