RF Probe

Most designs are based around the 1N34A Germanium diode, Clifton Laboratories has an interesting article comparing the following 3 diodes as alternatives;

  • 1N5711 Schottky signal diode
  • 1N270 Germanium signal diode
  • 1N4148 Silicon signal diode

The 1N270 came out tops with the 1N4148 being the least desirable of the trio.

So why build a RF probe? Besides being handy for a number uses, the primary purpose for which I needed an RF probe is for detecting RF output from the finals of my TS820S when neutralising the new output tubes.
