In this tutorial we present an easy to build RF noise generator. Schematic, construction details as well as the measurement results are discussed here. Additional results from a Spice simulation are available on : http://kavea.free.fr

Step 1: Materials

  • 2 x BFR93A
  • 1 x 9V Zener diode (Panasonic DZ2409100L is used here)
  • 1 x 7812 voltage regulator
  • Prototype board
  • Couple of resistors and capacitors (see schematic)
  • Optional : 1 x SMA connector and 1 x Aluminium case
