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 ...

The amplification is pretty high because of the way the base is polarised. The RF signal detection is made with a Schottky diode that has a low voltage on junction and is operating at a high frequency ...

Over the years, the technology that is used to detect RF-signal levels has improved dramatically. From a primitive-diode beginning, it advanced to multi-function-detector integrated circuits (ICs).

The CPDETLS-4000 RF power detector suits low-cost RF power monitoring in general lab use. With a frequency range of 10 MHz to 4 GHz, it is a zero-bias Schottky diode intended for use as a large ...

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 ...

A diode-based power sensor converts the RF signal to a DC voltage signal using an RMS detector. At power levels below –20 dBm, the detector exhibits a linear relationship between the RF signal and the ...
