In switch and attenuator applications, PIN diodes control the radio frequency (RF) signal level without introducing distortion ... Photodiodes are used for the detection of optical communication ...

he was able to make an RF detector that works reasonably well. The microcontroller running the code is an ATtiny13 on a Sparrow board. He’s using an everyday LED as a detector diode and an ...

and other RF or microwave devices. PN junction diodes or general purpose diodes are designed for general-purpose applications. Schottky barrier diodes (Schottky diodes, Shottky diodes) are used mainly ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such ... that no active RF amplification ...
