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 ...

These diodes are often associated in voltage multipliers to achieve a sufficient voltage of 1V. A sensitivity of -27 dBm has even been demonstrated in CMOS technology 0.18 µm [3]. The aim of this ...

These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific ... radios is that no active RF amplification is used.
