A diode mixer or ring modulator (corrected circuit, thanks commenters!) Via Wikimedia Commons. There is a further place that you will encounter a diode switch, especially if you are interested in ...

The mixer circuit can be summarized in the following ... Gilbert-cell mixers are usually ac-coupled through capacitors. Second, the diode-bridge mixer requires an LO large enough to turn on ...

Conveniently, a widely used terahertz mixer is the Schottky diode, which in its simplest ... highly compact terahertz photonic integrated circuit—a solid-state terahertz transceiver comprising ...

The mixer sideband conversion is nominally 3 dB, while the transformer losses (balun losses) are about 0.75 dB on each side, and there are diode losses because of the series resistances of the diodes.

An uncomplicated circuit application of a ZD is the common shunt voltage regulator. If you have a Zener diode (ZD) of unknown characteristics or if you want to use reverse-biased transistor junctions ...
