When [b.kainka] set out to make the world’s simplest RF detector, he probably didn’t realize it would be as easy as it was. Consisting of only a handful of components and thirty eight l… ...

Modern high-performance transmitters require accurate monitoring of RF power, ... and TDMA (time-division multiple access) have obsoleted traditional approaches to RF power. Diode-based detectors have ...

After rectifying by diode D1, the signal is fed to a two-transistor highgain Darlington amplifier, T2-T3. Assuming that a 10-inch telescopic antenna is used, ... 144 MHz rf detector circuit schematic.

These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. ... The neat thing about crystal radios is that no active RF amplification is used.

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 ...

The diode's ability to rectify high-frequency signals will therefore be poor. For these reasons, pn-junction diodes are almost never used as RF detectors.

It has been proposed that high-frequency detectors based on the so-called spin-torque diode effect in spin transfer oscillators could eventually replace conventional Schottky diodes due to their ...
