FM radio discriminators seemed to offer up germanium diodes especially. Analog UHF TV tuners I thought generally used germanium diodes in their mixers. 1N82s seemed to be a common number there ...

The main is a Nautel NV20, and it has a +15V power supply that can source 600ma. Likewise, our backup (a BE FM10B) has two +15V power supplies, each of which has a usable output. By diode-combining ...

LC-tank circuit portion. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage.

The new “Josephson diode” operates in the absence of a magnetic field and could, the team says, lead to a new generation of faster, more energy-efficient electronics. Conventional diodes are put to a ...
