These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically range of wavelengths depending on ...

During WWII, germanium was primarily used in point-contact diodes for radar pulse detection. After the war, from the 1950s to the early 1970s, germanium’s development as a semiconductor in transistors ...

With nothing more complex than a germanium point-contact diode and an oscilloscope, you can quickly, easily, and cheaply resolve microwave signals, as we are shown with a 2.4GHz wireless mouse.

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...

Voila: two gold contacts just a hair-width apart. The whole triangle was then held over a crystal of germanium on a spring, so that the contacts lightly touched the surface. The germanium itself ...

From its germanium clipping diodes, which allow for dynamic playing, to its vintage-style all-metal housing (a rarity for Behringer) and gold finish, the pedal is uncannily Klon-like, albeit in ...

Scientists of the MPI for Nuclear Physics (MPIK) initiated the GERDA experiment in 2004, in order to check the results of the Heidelberg-Moscow experiment by using an innovative shielding approach in ...
