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 RF signal is picked up by an antenna and made to resonate by C1-L1. After rectifying by diode D1, the signal is fed to a two-transistor highgain Darlington amplifier, T2-T3. Assuming that a ...

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 ...
