DR. HELLER ELEKTRONIK was founded in 1995 by Dr. M. Heller, a former employee of Rohde & Schwarz in Munich. Based on his profound experience in RF electronics a series of Laser Diode Drivers as well as accompanying equipment arose.

Nature of business

  • high current / high efficiency CW Drivers for Laser Diodes and LED`s
  • ultrafast pulsed Laser Diode Drivers
  • high efficiency controllers for thermoelectric devices
  • RF Power Amplifiers / Q-Switch-Modulators
  • High efficieny / wide bandwidth Power Amplifiers for Piezo-Actuators



  • design of low noise to high power RF circuitryup to 12 GHz
  • design and realisation of customer specific test equipment for optoelectronic and RF devices
  • design of High Rel-electronics for aircraft and space applications

The outstanding sign of all products is an exceptional high signal quality even at the highest frequencies.

We support the customer on an individual base.
