Simple: The germanium diode was the first suitable diode I found in my parts collection. :-)
A regular silicon diode will not work. An appropriate Schottky silicon diode will do the job; see the Infineon app-note in the "PPS" of the website. Also, the point-contact (regardless of the semiconductor material) reduces the diode's junction capacitance, making it faster, i.e., more suited for RF applications.
- cushychicken 6y agoWhat's the typical forward voltage of the germanium diode vs a silicon diode's 0.7[V]? It's a neat hack! Long live the Rigol DS1054Z!
- nynyny7 6y agoI didn't measure it, but literature has a value of about 0.3 V for a germanium diode's forward voltage.
